In this study, fatigue crack growth rates (FCGR) of 7% nickel steel at room and cryogenic temperatures were evaluated using damage-coupled finite element analysis (FEA). In order to perform the computational fatigue analysis effectively, methods for coupling damage to FEA are introduced and adopted. A hybrid method including the damage-coupled constitutive model and jump-in-cycles procedure was...

in the present paper, the modal analysis on a full finite element model of an off-road vehicle. this vehicle was modeled in the catia software and then meshed in the hypermesh software. the free vibration analysis was conducted by the abaqus software. by applying an external displacement, the forced vibration analysis was also performed. as a result, natural frequencies and shape modes were ext...

ABAQUS offers the possibility to model non-linear isotropic materials as well as linear anisotropic materials. However, it is not possible to use these two capabilities at the same time in order to model anisotropic hyperelastic materials. Gurvich proposed to model such materials by means of the linear superposition of two fictitious materials: a linear anisotropic, and a hyperelastic isotropic...

A multilink suspension offers a good balance between ride and handling performance and packaging space efficiency. It is also complex in design due to changes in link loading and compliance at high articulation travel. Therefore, geometric and material non-linearity behaviors are important to consider when designing these types of suspension components. Structural topology optimization has been...

Abstract Non-load-bearing body, with an independent frame, is subject to gravity load provided by itself and load-bearing components, also excitation from the road engine, etc. Therefore, rigidity strength of frame must be ensured in design, so welding fabrication process extremely important. In this paper, basic characteristics are analyzed using finite element technology, displacement, stress...
