This paper presents nonlinear finite element (FE) models to predict time- and temperature-dependent responses of shape memory polymer (SMP) foams in the large deformation regime. For first time, an A SMP foam constitutive model is implemented ABAQUS FE package with aid a VUMAT subroutine thermo-visco-plastic behaviors. phenomenological reformulated adopting multiplicative decomposition gradient...

This study includes experimental and numerical investigations on fibre-metal laminate structures containing adhesive joints under static bending loads. Experimental tests were carried out Glare® 4B specimens manufactured in-house doubler joint features. Numerical analyses performed using Abaqus software including damage in the glass fibre reinforced polymer layers, ductile resin pockets (FM94 e...

in this paper, a general elastoplastic-damage constitutive model considering the effect of strain rate has been developed. the derivation of this model has been cast into the irreversible thermodynamics with internal variables within the fundamentals of continuum damage mechanics (cdm). the rate effect has been involved as an additional term into the plastic yield surface (dynamic plastic yield...

Abstract The axial compressive bearing capacity, failure modes, and mechanisms of carbon fiber-reinforced aluminum laminate (CARALL) columns with single-channel cross sections were studied in detail. In this study, two types short CARALL specimens a 5/4 configuration first fabricated using 2024-T3 alloy different fiber orientations ([0°/90°/0°] 3 , [45°/0°/−45°] ) via pressure-molding thermal-c...

In this research, the exponential stretched based hyperelastic strain energy was modified to provide the unstressed initial configuration. To this end, as the first step, the model was calibrated by the experimental data to find the best material parameters. The fitting results indicated material stability in large deformations and basic loading modes. In the second step, the initial pseudo str...

The accurate material modelling of poly-l-lactic acid (PLLA) is vital in conducting finite element analysis polymeric bioresorbable scaffolds (BRS) to investigate their mechanical performance and seek improved scaffold designs. To date, a large variety models have been utilised, ranging from simple elasto-plastic high fidelity parallel network models. However, no clear consensus has reached on ...
