the dissipated energy from periodic deformation is regarded as the main reason for heat generation and temperature rise inside the tire domain. however, the mechanical behavior of rubber parts is highly temperature dependent. in most performed investigations, the influence of thermal effects on stress/ deformation fields of pneumatic tires is ignored and just temperature distribution is conside...

This paper presents the use of techniques for simulating product qualification as well as for product testing of electronic hardware to be used in the United States Marine Corp’s Advanced Amphibious Assault Vehicle. The goal of integrating “up-front” virtual life assessment into the development environment is to increase overall product reliability and decrease overall product cost by decreasin...

The analytical solution of functionally graded piezoelectric hollow cylinder which is under radial electric potential and non-axisymmetric thermo-mechanical loads, are presented in this paper. Using complex Fourier series and estimation of power law for variations of material characterizations through the thickness, the electro thermo mechanical behavior of the FGPM cylinder is obtained. The st...

In this paper, new numerical modeling of material flow in the thermo-mechanical friction stir welding process is presented. In this numerical model, the discretization in space is derived by the meshfree Galerkin method using a Lagrangian meshfree convex approximation. The discrete thermal and mechanical equations are weakly coupled as the time advances using a forward difference scheme. A mort...

General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...

loading conditions and complex geometry have led the cylinder heads to become the most challenging parts of diesel engines. one of the most important durability problems in diesel engines is due to the cracks valves bridge area. the purpose of this study is a thermo-mechanical analysis of cylinder heads of diesel engines using a two-layer viscoplasticity model. in this article, mechanical prope...
