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...

In the present work, large deformation rate-dependent constitutive behavior of isotactic polypropylene is studied via an experimentally validated macroscale model. To analyze nonlinear response material, mechanical tests are conducted at room temperature and a phenomenological model proposed to describe viscoplastic yielding damage semicrystalline polymer. The based on finite elastic-viscoplast...

Steel plate shear walls (SPSW) have been used as the primary lateral force resisting system in buildings. Extensive analytical studies on steel plate shear walls in the United States, Canada, Taiwan and other countries have already validated the simple analytical model known as strip model to predict the monotonic behavior of this kind of structural system. However, more research is still neede...

High precision reduction gears are used in the many industrial robots around the world. In order to respond to increasing demand for high durability under higher loads within a limited space, Nabtesco has been striving to analyze the whole assembly of high precision reduction gears for industrial robot arm joints. Initially, an analysis under static load (torque) was attempted using Abaqus/Stan...

Turon’s methodology for determining optimal analysis parameters for the simulation of progressive delamination is reviewed. Recommended procedures for determining analysis parameters for efficient delamination growth predictions using the Abaqus/Standard cohesive element and relatively coarse meshes are provided for single and mixed-mode loading. The Abaqus cohesive element, COH3D8, and a user-...

This paper aims to investigate the train-induced ground vibration and appropriate countermeasures using numerical modeling by Abaqus. First, the effect of appropriate boundary modeling in wave propagation studies is addressed by illustrating the application of nonreflecting boundaries in Abaqus using infinite elements. Second, the propagation of waves in the ground was investigated by applying ...

In this paper, a finite element modeling via ABAQUS/Explicit simulation on a novel fabrication miniature composite fuselage structure is presented. The fuselage structure is modeled as a continuum composite layup that consisted of a woven C-glass fiber/epoxy 200 g/m 2 composite laminated [908] with the orthotropic elastic material properties and adhesively bonded butt joint. The adhesively bond...
