Description:

In this test the simple shell system, depicted above, is analysed for an axisymmetrical state, with an edge compression of 100 MPa, which is equivalent to a line load of 10000 kN/m for a thickness of 0.1 m, whereby an isotropic material with an E-modulus of 210*10³ MPa and a poisson's ratio of 0.3 are used. For case 1 the system is generated with an element mesh of 2x2 quadrilateral elements. In the subsequent cases the number of elements are doubled, up to case 5, which then has 32x32 quadrilateral elements. The calculation was made with the program TALPA, because only this program can analyse an axisymmetrical state.

Results: Stress Szz (Stt) in point C. Benchmark value 237 MPa (8x8 elements). Deviation of program TALPA in loadcase 1 (2x2) 3.3 %, loadcase 2 (4x4) 3.3%, loadcase 3 (8x8) 4%, loadcase 4 (16x16) 4%, loadcase 5 (32x32) 3.8%
