No.556 Compression test analysis of trapezoidal rubber with a hole(The Hole Diameter 20mm)

The results of compression test analysis of trapezoidal rubber with a hole diameter of 20 mm are shown. Hexahedral solid elements, single point integration, with Hourglass control Type6 were used for the rubber model. LS-DYNA has outstanding performance in analysis regarding large deformation of rubber including buckling behavior.

Keywords: Hexahedral solid element, elform=1, hourglass control type 6

Tools: LS-PrePost ver.4.9, LS-DYNA MPP Win64 R13.1.0
