: Despite accuracy issues, TET4 is popular because it allows for easy and robust automatic meshing of complex 3D geometries. Relevant Academic Literature
: These elements are known to "lock" (over-stiffen) when simulating nearly incompressible materials or bending deformations, leading to results that underestimate true solutions. tet4.rar
: TET4 elements can only represent a constant strain state, which often requires a very fine mesh discretization for accurate results. : Despite accuracy issues, TET4 is popular because
Papers discussing TET4 elements generally address the following characteristics: : Despite accuracy issues
If you are looking for specific papers that extensively use or analyze TET4 elements, consider these examples:
