The response over the low-velocity impact of various shape impactors on a glass fiber reinforced polymer composite has been numerically analyzed with hemispherical, flat, partially flat and truncated shaped impactor used to analyze behavior resistance GFRP at speeds. numerical analysis was carried out using finite element software, ABAQUS (Dynamic/Explicit). To assess laminates while impacting,...

This paper presents an effective three-dimensional (3D) nonlinear explicit dynamic meshfree algorithm for the simulation of soft tissue mechanical responses. In the algorithm soft tissues are considered to be hyperelastic and nearly incompressible materials. The algorithm is based on the element-free Galerkin (EFG) method using total Lagrangian formulation and moving least square (MLS) approxim...

one of the bellows producing method is hydroforming process .whereas some factor of hydroforming process specially internal pressure affects on final characteristics produced bellows such as bursting, wrinkling and wall thickness distribution. in this paper the effect of internal pressure factor in final quality of produced bellows will be investigated. in simulation of process, abaqus/explicit...

Poly lactic acid (PLA) is widely used for the manufacture of biodegradable stents (BDSs). It was observed and investigated that tensile loads can significantly affect the degradation rate of PLA in our previous study. Additionally, non-uniform degradation can arise from complicated stress distributions in implanted stents under long-term and pulsatile tensile loading. The objective of this work...

We analyze the damage initiation, damage progression, and failure during 3-dimensional (3-D) elastoplastic deformations of a fiber reinforced polymeric laminated composite impacted by a low speed rigid sphere, and compare computed results with experimental findings available in the literature. Damage is assumed to initiate when one of Hashin’s failure criteria is satisfied, and its evolution is...

Abstract A numerical model based on the finite element framework was developed to predict seismic response of saturated sand under free-field conditions. The used a non-linear coupled hypoplastic u-p formulation simulate behaviour sand. constitutive implemented as user-defined routine in commercial ABAQUS explicit 6.14. Results centrifuge experiments simulating site layered system were validate...

In this study, the dynamic responses under blast loading of carbon fiber reinforced aluminum alloy laminates with different curvature radii, numbers layers, and layer directions were compared numerically. The finite element models built ABAQUS/Explicit. To calibrate numerical models, experiments on curved modeled, results showed good agreement experimental data. calibrated used to simulate resp...
