Closed-form stiffness matrices for higher order tetrahedral finite elements

Closed-form expressions for straight-sided isoparametric tetrahedral finite element stiffness matrices up to p-level 3 have been shown to offer significant time savings when compared to numerical integration. In this work, the development of closed-form stiffness matrices is extended to the next lev...
