In this paper, stress initialization methods, including their principles and operating procedures for reproducing steady in-situ stress state in LS-DYNA, are first introduced. Then the most popular four methods, i.e., explicit dynamic relaxation (DR) method, implicit-explicit sequence method, ...
The potential in industrial application of IGA has recently ignited the efforts to integrate IGA into commercial software packages such as Abaqus [28], [29] and LS-DYNA [30], [31]. Isogeometric shape and topology optimization has been an active research area since the introduction of IGA. ...
