Efficient computational homogenization of simple elasto-plastic microstructures using a modified Ritz-Galerkin approach Wulfinghoff, Stephan; Reese, Stefanie (CIMNE, 2015)
Open AccessIn this presentation, a recent work  on a fast nonlinear homogenization method for simple microstructures is revised. The degrees of freedom of the approach are defined on shear bands. Moreover, the number of degrees ...
Modeling the hall-petch effect with a gradient crystal plasticity theory including a grain boundary yield criterion Wulfinghoff, Stephan; Bayerschen, Eric; Böhlke, Thomas (CIMNE, 2013)
Open AccessAbstract. A strain gradient crystal plasticity theory including the gradient of the equiv- alent plastic strain ∇γeq is discussed. A grain boundary yield condition is proposed in order to account for the ...
