Compressive deformation of expanded polylactic acid resin subjected to quasi-static and dynamic loadings at wide temperatures

Many kinds of polymer foams are used in various situations. Especially, polymer foams are often used for shock absorber, therefore, there are many studies focusing on the effect of strain rate on the compressive properties, such as strength and absorbed energy. Since, most of them is produced from p...
