The brakes must be strong enough to stop the vehicle within a minimum distance in an emergency. The driver must have proper control over the vehicle during emergency braking and vehicle must not skid. The brakes must have good antedate characteristics their effectiveness should not decrease with prolonged application and thus it demand that the cooling of the brakes should be very efficient. Fo...

Often, time dependent and dissipative material behaviour is observed simultaneously with load depending stiffness reduction. For example, filled elastomers and biological tissues belong to this class of materials. Both phenomena, i.e. viscoelasticity and damage, are incorporated into a formulation of finite strain elasticity. The phenomena either can be used together or one or the other feature...

the purpose of this study is to identify parameters influence on the particle deposition within fin and tube heat exchanger of air-conditioning systems by cfd analysis. first the basic sketch of periodic geometry drawn and meshing operation including boundary conditions was performed. then the gas side properties and flow parameters were solved by ansys fluent 14.5 software. lagrangian equation...

shot peening applies a residual compressive stress field (rcsf) on the surface of parts. it also shifts “crack nucleation sites” to sub-surface locations. a nondestructive method of measuring the stresses, sin2ψ was utilized here and the stress values introduced to ansys software. for this purpose, uniform stress in all directions was applied on the con rod. loading on the rod in ansys had thre...

Engineers use the breadth and depth of leading simulation software to predict how products will behave in multi-domain operating environments. Product behavior nearly always involves different types of physical phenomena, to one degree or another. Temperature differences can influence mechanical stress, for example, and air flow around a structure may impact acoustics or change structural loadi...

A finite element scheme for simulation of welding residual stresses is presented in this paper. Detailed thermal and residual stress analyses for butt-welded and socket-welded pipes are performed using ANSYS and ABAQUS. The calculated distribution of axial stress and hoop stress at welded joint are validated against experimental results. Furthermore, residual stress relaxation under high amplit...
