We aim to model fracture on pressure vessel surfaces so that its rupture can be avoided. It is well known that pressure vessels have wide-spread applications in almost all industries. They are often subjected to high pressures and extreme temperatures and in some typical applications they even carry highly flammable or hazardous substances. In the presence of cracks, the state of stress near the fracture zone becomes very high, due to the phenomenon of stress singularity at the crack tips. This greatly reduces the strength of the material and can lead to early failure. In this paper, the geometry of pressure vessels is discretised using splines which are used as the basis for isogeometric analysis (IGA). Initially, the stress analysis of thin pressure vessel is carried out in the absence of cracks by implementing IGA-based Kirchhoff-Love shell theory, and the results are compared with analytical or standard available solutions. The crack is assumed to cross the entire thickness and is introduced either in axial or circumferential direction.

In micromouse competitions, small autonomous robots move in a maze and turn into corners with steep angles at high speeds. However, the recent competition was marked by speeding up. Generally, driving performance is limited through only the motor current control braking. Therefore, in this study, we developed a mechanical brake device using electrorheological fluid (ER fluid). Around the robot's drive, this brake device is connected to the DC motor through gears, and when the robot decelerates, the decelerating time is shortened if the ER brake is used together with the electric DC motor brake, so the deceleration time before a corner is shortened. Thus, the movement time from start of the maze to the goal is also shortened. Aiming at improving the performance of small robots that participate in micromouse competitions, we reported the basic research, performance evaluation, and brake design of a small brake that uses ER fluid.

Herein, nanotechnology efficacy on the acute velocity of fluid of fluid-conveyed-nanocomposite pipes is studied. The polymeric pipe is armed by carbon nanotubes utilising Mori and Tanaka model. The dynamic force induced by fluid is calculated utilising perturbation method. Based on method of energy and Lagrange model as well as Mindlin theory, the final equations are obtained. Utilising semi-exact solution, the relations are solved in order to calculate the acute velocity of fluid so that the efficacy of pipes geometrical constants and CNT percentage are investigated on the acute velocity of fluid. The outcomes are compared with other papers for showing the accuracy of this solution. With adding the CNT percentage, the acute velocity of fluid is improved. Indeed, the heat generation has a harmful efficacy on the acute velocity of fluid since it can reduce the acute value due to reduction in the stiffness of pipe.
