Recent Enhancements and Studies of Isogeometric Shells in LS-DYNA
Isogeometric Analysis (IGA) [1] is a Finite Element Analysis (FEA) technology that uses spline basis functions known from Computer Aided Design (CAD) to describe the geometry and the solution field. Employing such spline basis functions with higher order and higher continuity may yield several advantages such as an easier transition from CAD to analysis, a more accurate geometry description, smooth solution fields or a larger time step in explicit analysis. In fact, only the higher-continuity property of splines enables the concept of trimming (ubiquitous in CAD) to be used in explicit analysis with a feasible time step size [2].
