OS-V: 0500 Laminated Strip
Test No. R0031/1 OptiStruct examines the bending stress at E, Interlaminar shear stress at D and the z-deflection at E for linear static analysis.
Benchmark Model
Quad4 and Hexa8 elements are used to create one quarter model of the laminated strip simply supported at A. For Quad4 elements Ply laminates are created and for Hexa8 elements PSOLID property is used. A line load of 10N/mm is applied at C.
