Capturing anisotropic constitutive models with WYPiWYG hyperelasticity; and on consistency with the infinitesimal theory at all deformation levels

De Rosa, Erica; Latorre, Marcos; Montáns, Francisco Javier (Elsevier, 2017-11)

[EN] The elastic nonlinear behavior of fiber-reinforced materials and soft biological tissues is analyzed using anisotropic hyperelastic models. Frequently, these models are not compatible with the corresponding infinitesimal ...
Computational anisotropic hardening multiplicative elastoplasticity based on the corrector elastic logarithmic strain rate

Sanz, Miguel Á.; Montáns, Francisco Javier; Latorre, Marcos (Elsevier, 2017-06-15)

[EN] In this paper we present a new computational framework for anisotropic elastoplasticity with mixed hardening which presents the following characteristics: (1) it is motivated by a one-dimensional rheological model ...
Sheet metal forming analysis using a large strain anisotropic multiplicative plasticity formulation, based on elastic correctors, which preserves the structure of the infinitesimal theory

Sanz, Miguel A.; Nguyen, K.; Latorre, Marcos; Rodríguez, Manuel; Montáns, Francisco Javier (Elsevier, 2019-10-15)

[EN] Sheet metal forming is a very important process in industry to create a wide variety of goods. The analysis of local ductility and residual stresses is important both to assess the viability of the manufacturing process ...
