Hybrid fiber-reinforced polymer composites comprised of glass and steel fibers in a resin matrix have been shown to increased strength energy dissipation compared conventional composites. However, methods for simulating the mechanical behavior combinations hybrid yet be advanced. In this study, non-hybrid with off-axis were manufactured extracted coupons subjected half-cyclic tensile testing. T...

In the context of nuclear waste disposal, the modelling of the behaviour of host rocks and soils still needs improvement. Unsaturated porous geomaterials exhibit particular behaviour when exposed to suction. Their non-linear behaviour may result from two different processes, plasticity which induces irreversible strains and damage which causes a deterioration of their elastic properties. Many e...

A new relaxation approach is proposed which allows for the description of stress- and strain-softening at finite strains. The model based on construction a convex hull replacing originally non-convex incremental stress potential in turn represents damage terms classical (1?D) approach. This given as linear combination weakly strongly damaged phases thus, it homogenization microstructure bifurca...

We present a new Integrated Finite Element Neural Network framework (I-FENN), with the objective to accelerate numerical solution of nonlinear computational mechanics problems. leverage swift predictive capability neural networks (NNs) and we embed them inside finite element stiffness function, compute element-level state variables their derivatives within nonlinear, iterative solution. This pr...
