Abaqus Crushable Foam with Rate Dependency (*ELASTIC, *CRUSHABLE FOAM, OPTION=RATE DEPENDENT)


Test ID

G-725

Description

Test are performed in compression on foams that exhibit crushing with a Poisson's ratio that is essentially zero. The following tests are performed; A density test, a confined compression test, two low speed uniaxial compression tests, and three high speed uniaxial compression tests . From this data both an *ELASTIC as well as a *CRUSHABLE FOAM model are created including the required hardening rule and the rate dependency parameters.

Included Tests

1x D-010 Solid Density
2x M-210 Compressive Stress-Strain, Strength and Modulus
1x M-213 Confined Compression Stress-Strain (Hydrostatic, for rubbers)
2x M-231 High Speed Compressibility of Foams and Elastomers

Options

If Rate Dependency is not required please select test [G-724].

Samples

: 30 prisms

Application

This model is useful for simulations that involve the use of materials that exhibit crushing behavior with rate dependency, especially useful for packaging materials. It is not recommended for recoverable foams.
