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...

• High-speed imaging and DIC are used to track damage progression during impact test A proposed 3D FE model allows predicting the behavior of laminate composites [0/90] 3s laminates failed due fiber breakage at high compression impacted region [±45] exhibited matrix cracking delamination caused by tension The aim this paper is describe dynamic biaxial glass reinforced under low velocity through...

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...

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...

For implementation&#10 of the free surface boundary condition, a new subroutine has been introduced to an existing steady 3-D body fitted code. This code was previously written for steady flow simulation in closed ducts. The algorithm used in this subroutine reduces the instability problem according to the free surface wave generation. For code validation, it was applied to two different open c...

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 companion article, we present within the finite element context the numerical algorithms for the integration of the thermodynamically consistent formulation of geometrically nonlinear gradient-enhanced viscoinelasticity derived in the first part of the article. The proposed unified integration algorithms are extensions of the classical rate-independent return mapping algorithms to the r...

We propose the collection, standardization, and distribution of a full-featured, production quality library for reliable scientific computing with routines using interval techniques for use by the wide community of applications developers. 1 Vision – Why are we doing this? The interval/reliable computing research community has long worked to attract practicing scientists and engineers to use it...
