Least-squares finite strain hexahedral element/constitutive coupling based on parametrized configurations and the Löwdin frame
Two novelties are introduced: (i) a finite-strain semi-implicit integration algorithm compatible with current element technologies and (ii) the application to assumed-strain hexahedra. The Löwdin algo- rithm is adopted to obtain evolving frames applicable to finite strain anisotropy and a weighted l...
