Product: ABAQUS/Standard

S3 S3R S4 S4R S4R5 S8R S8R5 S9R5 STRI3 STRI65

Material:

Linear elastic, Young's modulus = 1 × 10³, Poisson's ratio = 0.3.

Boundary conditions:

at nodes , , and , at all nodes along the perimeter.

Loading:

–2.0 at node , 20.0 at nodes and , –20.0 at nodes and , 10.0 at nodes and , –10.0 at nodes and .

Displacements: –12.48.

*A refined mesh consisting of two elements is used for the S8R model since hourglassing occurs in a one-element mesh.
