EFFECTS OF HIGH-RATE COMPRESSION LOADING ON SHORT REINFORCED PLASTIC MEMBERS
Abstract
The behavior of structural plastic components when they are loaded rapidly in compression is investigated. The specific objective of the phase of the work described in this report is to redesign and improve the present high-rate compression tester. The test pieces used were of three types: short, thin-walled tubular aluminum columns, solid columns of cellular cellulose acetate, and tubular epoxy columns. Permanent deformations of both the tubular aluminum columns and the solid cellular cellulose acetate columns appeared to occur intermittently as the columns resisted series of maximum loads as deformations progressed. The intervals between the points of maximum resistance were relatively uniform for the aluminum columns, but were varied for the cellular cellulose acetate test pieces. the epoxy columns gave the least reproducibility, shattering severely under load. It was concluded that the present construction of the compression tester requires major modifications. Terminal conditions cannot be controlled. It was established that an optical system to simultaneously record deformations along successive increments of length of columns during testing should be integrated into the test system. (Author)
