| Description: | In this test the shell system, depicted above, is analysed with a distributed load of 1 MPa = 1000 kN/m², whereby an isotropic material with an E-modulus of 210*10³ MPa and a poisson's ratio of 0.3 are used. The system is generated in such a manner, so as to allow the calculation of several different element meshes consisting of quad-elements. The following element meshes are investigated: 3x3 elements, 6x6 elements and 12x12 elements. The calculation is made with the program ASE. More precise description: NAFEMS: Linear Statics Benchmarks, Vol. 1 Results: Stress Syy (Saa) at point A. Theoretical value -69.1 MPa analytically. Benchmark value -68.89 MPa (6x6 element mesh with 8-node quad-elements). Deviation of program ASE from the analytical results in case of 3x3 elements 8.0 %, in case of 6x6 elements 3.9 %, in case of 12x12 elements 4.2 %. Further results in the DAT-file. |
