Nonlinear Modeling of a Sustainable Material
This study developed a nonlinear constitutive model for a sustainable orthotropic material. Existing methods for constitutive models of wood were improved upon to include the nonlinear stress-strain response not only in the two orthogonal axes but at any orientation to the strong axis of the …

Estimation of nonlinear mechanical properties of atherosclerotic plaques
… were employed to construct finite element models which were subsequently used in conjunction with a genetic algorithm to determine the parameters in a nonlinear constitutive model. A new multi-frame scheme is introduced to better perform the estimation on a nonlinear mechanical model and …

Thermoviscoelastic characterization and predictions of Kevlar/epoxy composite laminates
… to accelerate the characterization process. A nonlinear constitutive model was developed to describe the stress dependent viscoelastic response for each of the material properties. A new numerical procedure to predict long term laminate properties from lamina properties (obtained …

Simulations of deformations and fracture of biological materials
… to the pressure of a surgical tool. Secondly, we model the deformation of a cortical bone due to microindentation. Thirdly, we model the fracture of cortical bone under a uniaxial tensile load by using an extended finite element method. Finally, we evaluate how an arrangement of curved mineral …
