Breaking Strain Measurement of ABS Resin

Introduction

Increasingly high performance engineering resins are being developed for use in a wide range of fields, such as the automotive industry, consumer electronics, office automation equipment, for their various functional characteristics. Some of the criteria that have become especially important for evaluating the performance of such materials is impact resistance and its associated material properties, such as strength and rigidity. In addition to evaluating materials in terms of conventional static tensile strength, high-rate tensile strength, longitudinal elasticity, and strain measurements up to the breakpoint are expected to become important new parameters for materials development. This example describes testing the high- rate tensile strength of a flat plate specimen of ABS resin and measuring strain up to the breakpoint. Images of the high-rate tensile test were captured with a high-speed video camera and image analysis software was used to measure the strain between gauge length on the specimen.
