Study of mechanical properties of biodegradable polymers by tensile testing and instrumented indentation methods

Abstract

Tensile testing and instrumented indentation of biodegradable polymers have been performed. The elastic modulus, yield strength, and ultimate tensile strength of polymers were determined by a non-destructive (instrumented indentation) method. The registration of an instrumented indentation diagram may contribute to increase efficiency of on-line mechanical inspection of biodegradable polymer products during their manufacturing by additive technologies, and then in operation.
