Currently, one of the most popular in fracture mechanics is taking into account damage and its effect on stress-strain state structural elements. In this work, Lemaitre model was integrated taking, combined hardening law, which combines Armstrong - Frederick kinematic law Voce isotropic ANSYS finite element software. The implemented form a dynamically linked library user material for three-dime...

In order to investigate the behavior of elastoplastic composites exhibiting both isotropic and nonlinear kinematic hardening, we extend Double Incremental Variational (DIV) formulation Lucchetta et al. (2019), based on incremental variational principles introduced by Lahellec Suquet (2007) proposed Agoras (2016). However, Armstrong-Frederick model (Armstrong Frederick), which is very often used...

Wrinkling, developed due to compressive instability, is one of the main failure modes in deep drawing processes. Depending on die geometry and blank holder force, it can be observed as flange wrinkling and/or side-wall wrinkling. In this study, cylindrical cup process investigated by using different constitutive models that are formed CPB06ex2, Hill’48, BBC2008-8p BBC2008-16p yield criteria wit...

In this paper an e cient sequential approach for simulating thermal stresses in brake discs for repeated braking is presented. First a frictional heat analysis is performed by using an Eulerian formulation of the disc. Then, by using the temperature history from the rst step of the sequence, a plasticity analysis with temperature dependent material data is performed in order to determine the co...

The construction of regularization operators presented in this work is based on the introduction of strain or damage micromorphic degrees of freedom in addition to the displacement vector and of their gradients into the Helmholtz free energy function of the constitutive material model. The combination of a new balance equation for generalized stresses and of the micromorphic constitutive equati...
