This article concerns a theoretical analysis of heat conduction in a transient state and the associated thermoelastic behavior for a multilayered anisotropic laminated plate subjected to nonuniform heat supply. As an analytical model, we consider a laminated rectangular plate consisting of a diagonal stack of layers having orthotropic material properties, i.e., an angle-ply laminate. The three-dimensional temperature solution in a transient state and the associated thermoelastic behavior of the plate with simply supported edge conditions are formulated using the functional approach based on the variational principle. For the analysis of the thermoelastic field, the higher-order shear deformation theory of the plate is used to evaluate the shear stress components. As an example, numerical calculations are carried out for a 2 layered angle-ply laminate, and the numerical results for temperature distribution, out-of-plane deflection, normal and shear stress distributions are discussed in detail.

The dependence of slip band occurrence at the periphery of microcircular holes formed by photoetching in electrodeposited copper foil upon the number of cycles and cyclic stress magnitude for plane bending and cyclic torsion is examined. The results show that the principal stresses in an element under biaxial stresses, which are undetectable by the conventional copper electroplating method, can be evaluated using an equation based on the probability of slip occurrence, which takes into account both cyclic stress magnitude and the number of cycles.

This paper is dedicated to the problems of nondestructive testing of rubberlike materials. A new method which we call an audiosonic contact impedance evaluation is developed. It is based on mechanical contact impedance evaluation (MCIE) at the local contact area between a piezo active sensor and specimen. A theoretical model consisting of quasistatically loaded and consequently connected dissipative Voigt's elements is discussed and solved analytically. A resonance equation used for MCIE at the local contact area consists of two impedances: mechanical impedance of PZT sensor and mechanical impedance of the specimen. Analytical results are compared with the results obtained from the simulation using the finite element method (FEM). Simultaneous measurements of the contact impedance and compliance associated with rubberlike materials having different hardnesses are accomplished by the multilayered piezo active sensor. A dynamic response obtained from the experimental sensor highly correlates with mechanical and rheological parameters.

This paper is concerned with an analytical formulation and a numerical solution of the thermal stress and deformation for axisymmetrical shells of functionally graded material(FGM) subjected to thermal loading due to fluid. The temperature distribution through the thickness is assumed to be a curve of high order, and the temperature field in the shell is determined using the equations of heat conduction and heat transfer. The equations of equilibrium and the relationships between the strains and displacements are derived from the Sanders elastic shell theory. The fundamental equations derived are numerically solved using the finite difference method. As numerical examples, functionally graded cylindrical shells composed of SUS 304 and ZrO 2 subjected to thermal loads due to fluid are analyzed. Numerical computations are carried out for various compositional distribution profiles in FGM. The results show that the present method gives correct temperature distributions and that the temperature distributions, stress distributions and deformations vary significantly depending on these compositional distribution profiles.

In this work, a theoretical analysis of the axisymmetric thermal stress problem and the associated thermal stress intensity factor K 1 is developed for Kassir's nonhomogeneous body with a penny-shaped crack with radius a subjected to a uniform heat supply from the crack surfaces. Assuming that the thermal conductivity λ, shear modulus of elasticity G and coefficient of linear thermal expansion a vary with the axial coordinate z according to the relations λ(z)=λ 0 (|z/a|+1) β , G(z)=G 0 (|z/a|+1) m and a(z)=a 0 (|z/a|+1) n , the axisymmetrical steady temperature solution is obtained. Then, the associated thermal stress distribution and the thermal stress intensity factor at the crack tip are evaluated theoretically using the method of superposition. Numerical calculations are carried out for three different cases taking into account the nonhomogeneity of the above-mentioned material properties, and the numerical results obtained are shown in graphical form. The influences of the nonhomogeneous material properties on the temperature distribution, the corresponding thermal stress distribution and the stress intensity factor are examined.

To simulate not only plastic deformation of a workpiece but also that of a shot in a peening process, the effect of the interaction between the shot and workpiece in the collision is included in the dynamic rigid-plastic finite element method. In the formulation, the equilibrium equations of nodal forces are solved simultaneously with velocity boundary conditions at the interface between the workpiece and shot for sliding and non-sliding contacts. Axi-symmetric plastic deformation in peening of a circular workpiece with a single shot is computed. The calculated shapes of the workpieces and the shots are in good agreement with the experimental ones for plasticine workpieces and shots. It is shown that almost no plastic deformation of the shot occurs under actual shot-peening conditions for steel workpieces when the flow stress ratio of the shot to the workpiece is larger than two.

Oxidation kinetics of as-received and preheat-treated C/C composites fabricated by the preformed yarn method were investigated. The weight loss due to gasification was measured with oxidation time. In situ observation of microscopic morphological change due to oxidation was conducted using a laser microscope during heating in flowing air. Then, degraded inner and outer morphologies of C/C composites oxidized at various temperatures were examined through observation by SEM and measurement of pore distribution using a mercury porosimeter. As a result, degraded morphologies due to oxidation were extremely different depending on the oxidation temperature range. The inner structural changes became obvious as the oxidation temperature decreased. Therefore, the rate-determining process of the oxidation was changed from the surface chemical reaction to reactive gas diffusion across the boundary layer of a gaseous oxidation product as the oxidation temperature increased. The oxidation reactivity of C/C composites was related to metallic impurities such as iron and residual stress generated during fabrication.

In order to investigate crack growth characteristics due to thermal striping in liquid sodium coolant used for fast breeder reactors (FBRs), thermal striping tests in sodium have been conducted using Type 304 stainless steel and material produced by plasma carburizing Type 304 stainless steel. The results showed that the threshold stress intensity factor range, derived from a thermal stress analysis under the condition of plane stress, could be used to predict the final lengths of the nonpropagating cracks. The depths of nonpropagating cracks increased with increasing carbon content. This tendency was attributed to the difference of the stress intensity factor range, caused by the difference in Young's moduli of the materials.

Crack propagation tests were carried out in various environments from water to vacuum using compact tension specimens. The main results obtained are as follows: (1) In vacuum, the crack propagation rate under cyclic load is faster than that under static load. Cyclic fatigue can occur without the presence of water vapor. This behavior is substantial cyclic fatigue in this material. (2) The degree of crack propagation rate acceleration increased as partial pressure of water vapor rose. (3) These results are explained by the mechanism in which the origin of the cyclic effect is the decrease in the stress shielding effect by cyclic load. In this respect, the only necessary condition for cyclic fatigue is not stress corrosion cracking due to water vapor but load cycling.

When a transversely isotropic solid cylinder is subjected suddenly to a uniform temperature rise, a stress wave occurs at the surface the moment thermal impact is applied. The stress wave at the surface proceeds radially inward to the center of the cylinder. The wave may accumulate at the center and give rise to very large stress magnitudes, even though the initial thermal stress is relatively small. This phenomenon is called the stress-focusing effect. In this paper we analytically analyze the effects of these waves using the ray series. The results give clear indications of the mechanism of the stress focusing effect in a transversely isotropic solid cylinder.
