METHOD FOR TESTING CELLULAR RIGID PLASTICS ON STATIC PURE BENDING

摘要

A method for testing cellular rigid plastics on static pure bending includes application of static load to the middle of the sample with working length l, arranged as a tetrahedral prism with rectangular cross section. One applies to the sample two same static forces P at two equal by value and applied symmetrically from the supports at distances 3/10 l, this provides its pure bending.
