Abstract
The influence of strain rate on the compressive strength and the absorbed energy of polylactic acid resin foam which is low environmental load plant-derived plastic was experimentally studied by conducting compression tests at strain rates from 10^<-3> to 170 s^<-1>. It was found that the flow stress of polylactic acid resin foam during deformation and the absorbed energy up to the strain of 0.6 increased with the increase of strain rates. The compressive strength of the foam was also strongly dependent on the density of specimen, despite the same material.
