The present paper aims at providing a comprehensive investigation of the abilities and limitations strain gradient crystal plasticity (SGCP) theories in capturing different kinds localization modes single crystals. To this end, small deformation Gurtin-type SGCP model recently proposed by authors, based on non-quadratic defect energy uncoupled dissipation assumption, is extended to finite defor...

Strain smoothing methods such as the smoothed finite element (S-FEMs) and strain-smoothed element~(SSE) method have successfully improved performance of elements, there been numerous applications them in analysis. For sake efficient to large-scale problems, it is important develop a mathematically numerically well-elaborated iterative solver for strain methods. In this paper, inspired by spectr...
