http://web.mit.edu/kjb/www/Principal_Publications/Improved_stresses_for_the_4_node_tetrahedral_element.pdf WebIn this paper, a new 4‐node hybrid stress element is proposed using a node‐based smoothing technique of tetrahedral mesh. The conditions for hybrid stress field required are summarized, and the field should be continuous for better performance of a constant‐strain tetrahedral element. WebThe SOLID45 element can be degenerated to a four-node tetrahedral configuration with three DOF per node. The tetrahedral configuration is more suitable for meshing non-prismatic geometry, but is less accurate than the hex configuration.
