Minimum specimen size for composite testing at low temperature.

Author(s) : ABDELMOHSEN H. H.

Type of article: Article

Summary

The article demonstrates analytically the minimum specimen size required to evaluate composite mechanical properties at low temperature. Small specimen size reduces the need to use large amounts of cooling liquid for testing purposes. The solution is general and it is intended to quantify the specimen dimensions and the constrained edge effect on composite mechanical testing. The results illustrate the effects of specimen geometry and degree of anisotropy of the material on the minimum specimen gauge length. Examples are given concerning glass-epoxy, graphite-epoxy and boron-epoxy.
