Smoothing of yield surfaces and a reformulation of multi-surface plasticity [PDF]
, 2011 In this work we describe a procedure for the smoothing of non-regular yield surfaces and plastic potential functions. We also present several application examples corresponding to different well-known cases. Moreover, we show that a multi-surface plasticity model can be reduced to a model with a single yield surface by using the same smoothing ...

Prediction of necking in HCP sheet metals using a two-surface plasticity model [PDF]
, 2019 In the present contribution, a two-surface plasticity model is coupled with several diffuse and localized necking criteria to predict the ductility limits of hexagonal closed packed sheet metals.

A numerical study of crack shielding and deflection under extensive plasticity [PDF]
, 2009 Experimentally observed crack deflection events in multi-layered material systems, occurring even under pure mode-I loading, are here simulated and explained through elasto-plastic finite element modelling.

Surface profile prediction and analysis applied to turning process [PDF]
, 2008 An approach for the prediction of surface profile in turning process using Radial Basis Function (RBF) neural networks is presented. The input parameters of the RBF networks are cutting speed, depth of cut and feed rate.

Numerical Modeling of an Elastic Spherical Contact under Combined Normal and Tangential Loading
Revue Nature et Technologie, 2023 The Contact between two surfaces with normal and tangential force involve friction dissipation phenomenon .The friction phenomenon can be formulated as a constitutive relation in a similar form to that of the elasto-plastic constitutive equation of ...
