Since the rotor blade system of an horizontal axis wind turbine is responsible for converting wind energy into mechanical, which turns into electrical and predicting its dynamic behavior is of vital importance. In that sense, this paper deals with performing a modal analysis of a blade belonging to the DTU 10-MW reference wind turbine by using a modified Myklestad’s method. The blade model was built on two different keystones, as follows: first, considering uncoupled bending in out-of-plane (flapwise) and in-plane (edgewise) directions and considering a coupled bending-torsion motion also in both directions. In order to accomplish these objectives, a Python code was implemented. The computed eigenfrequencies were compared to the results obtained for the blade by using the finite element method. Besides, the mode shapes were plotted and the centrifugal stiffening was also taken into account. Results suggest the feasibility of the modified Myklestad’s method for modal analysis purposes, since good agreement with reference data was achieved and considering that the Myklestad’s method has a considerably less complex implementation than the finite element method.

The paper describes analytical and numerical solutions for five selected domes (a spherical shell, a geodesicisotensoid shell, a shell with zero transversal strain, a shell with zero transversal stress, and a shell with identical strain) for composite pressure vessels manufactured by means of filament (helical) winding. The stresses and strains in the domes were evaluated analytically from known equations with the use of MATLAB script for numerical evaluation and via finite element analysis (FEA) with Abaqus software and results were compared with each other. Two failure criteria, interactive and non-interactive, were chosen for the evaluation of critical areas of the shells. Moreover, the best dome shape for a given material and polar hole/equator ratio was selected for various types of failure, i.e., a loss of tightness/leakage or the failure of the fibers.

Impact studies are performed to evaluate the ballistic performance of material subjected to a high strain rate. At high velocities, the projectile penetrates through the material which leads to a fracture of the target body. The fracture behavior depends upon the condition of the target body. It is anticipated that the fracture behavior should depend upon the prestress condition of the target. Considering the aforementioned concern, the thermo-elastic-plastic finite element model is formulated using MSC Marc Mentat to analyze the effect of the prestress condition of the target body on fracture behavior. A detailed comparison has been presented considering four different prestress states subjected to impact by a blunt-shaped projectile. The continuum damage mechanics using a stress triaxiality-based damage model is used to simulate damage evolution and fracture. It is found that the presence of prestress alters the overall fracture response of the structure subjected to high strain rate deformation. In the presence of tensile prestress, the material resists the accumulation of damage which is due to the lower values of stress triaxiality and equivalent plastic strain. It is also found that the presence of tensile prestress inside the target body increases the ballistic performance, whereas the presence of compressive prestress inside the target body degrades the performance.
进行冲击研究是为了评估材料在高应变率下的弹道性能。在高速下,弹丸穿透材料,导致靶体断裂。断裂行为取决于靶体的状态。预计断裂行为应取决于目标的预应力条件。考虑到上述问题,利用MSC Marc Mentat建立了热弹塑性有限元模型,分析了靶体预应力条件对断裂行为的影响。考虑钝形弹丸冲击下的四种不同预应力状态,进行了详细的比较。采用基于应力三轴性的损伤模型,采用连续损伤力学方法模拟损伤演化和断裂过程。研究发现,预应力的存在改变了结构在高应变率变形下的整体断裂响应。在拉伸预应力存在的情况下,由于应力三轴性和等效塑性应变值较低,材料可以抵抗损伤的累积。研究还发现,靶体内存在拉预应力可提高靶体的弹道性能,而靶体内存在压预应力则会降低靶体的弹道性能。

This work is devoted to the systematic numerical simulation of oil displacement using nanosuspension with silicon oxide particles with concentration of up to 1 wt% and particle sizes of 5 nm. The influence of such factors as core wettability, concentration of nanoparticles, capillary number, and oil viscosity on the enhanced oil recovery by nanosuspension has been systematically investigated using the VOF method for 2D-dimensional micromodels. Various rocks were considered: dolomite, metabasalt and sandstone. It is shown that the oil recovery coefficient improves for all considered types of rock with increasing nanoparticle concentration. The most effective application of nanosuspension for enhanced oil recovery is observed at a low capillary number, corresponding to the capillary displacement mode. The addition of nanoparticles facilitates increasing oil recovery factor in a wide range of viscosity ratios between oil and displacement fluid.

Traditional engineeringmodels for addressing fatigue issues are based on empirical relations between the necessary number of cycles for fatigue failures $N_f$ and either, the nominal stress $sigma_{an}$ or the local strain $epsilon_a$ amplitudes. The aim of the present paper is to highlight the advantages of the local strain-based approach $epsilon N$ for fatigue assessment of notched components over the more traditional stress-based approach $sigma N$. Since a closed form solution for the ratio between fatigue life predictions among the two methods does not exist, we have considered a hypothetical case study that included variables such as the applied stress, the stress concentration factor and the structural material, and numerically calculated the expected fatigue life according to each approach. In order to highlight the differences related with the stress-strain analysis, the applied nominal stresses (uniaxial) were limited to the elastic region where both methods use approximately the same fatigue strength curve. Additionally a unique and equal function for accounting for themean stress effects was incorporated in both approaches. Fatigue life predictions are expressed in universal graphs of normalized stress versus the $N_f-ratio$, the latter parameter defined as the quotient between the $N_f$ predictions according to the $sigma N$ and $epsilon N$ approaches, considering the average values for a group of sixty structural steels at each load level. The results confirm that fatigue life predictions under the traditional stress based approach are conservative when compared to the strain based approach for all the possible scenarios described by the variables involved.

In this article, the two-phase water hammer theoretical and numerical simulation are provided. A mathematical formulation is presented to describe the transient one-dimensional flow of bubbly gas-liquid mixtures without phase change in an horizontal pipe. The features of the two-fluid model for simulating water hammer flows are investigated. The governing equations were obtained from mass and momentum conservation laws combined with interfacial interaction correlations. The obtained system of equations for steady-state is solved through the Runge-Kutta method. On the other hand, the transient flow equation solutions are provided by the Newton-Raphson methods. A laborious calculation was carried out to determine the common pressure of the two phases. In order to improve the robustness and efficiency of the Richtmeyer-Lax-Wendroff method in solving the two-fluid model, a flux corrected transport technique was proposed. The results obtained by the proposed model are compared successfully to the corresponding homogeneous equilibrium model and the experimental ones provided by the literature.

The boundary element method is used to analyze the problem of dynamic loading acting inside a cubic cavity located in a partially saturated poroelastic halfspace. Defining relations of a Biot’s porous medium are used, which are written in Laplace representations for unknown functions of displacements of the skeleton and pore pressures of the fillers. The boundary element methodology is based on using boundary integral equations of the direct approach. Solutions in time are obtained using the stepped method of numerical inversion of Laplace transforms. Dynamic responses of displacements and pore pressures at points on the surface of the halfspace and the cavity have been constructed. The effect of the values of the saturation coefficient and of the depth of the location of the cavity on dynamic responses has been studied.

Artificial Neural Networks (ANN) are designed to evaluate the pull-in voltage of MEMS switches. The mathematical model of a micro-switch subjected to electrostatic force is preliminarily illustrated to get the relevant equations providing static deflection and pull-in voltage. Adopting the Step-by-Step Linearization Method together with a Galerkin-based reduced order model, numerical results in terms of pull-in voltage are obtained to be employed in the training process of ANN. Then, feed forward back propagation ANNs are designed and a learning process based on the Levenberg-Marquardt method is performed. The ability of designed neural networks to determine pull-in voltage have been compared with previous results presented in experimental and theoretical studies and it has been shown that the presented method has a good ability to approximate the threshold voltage of micro switch. Furthermore, the geometric and physical effect of the micro-switch on the pull-in voltage was also examined using these designed networks and relevant findings were provided.
