โœฆ Synopsis

The variables to be considered and constraints to be fulfilled in the design of an impact tester are discussed. Solutions are proposed and the final design of the machine is described, including associated micro-computer based analysis-equipment. Some of the assumptions made by earlier workers are avoided.

This paper presents methods to determine two fracture mechanics parameters using loaddeflection curves obtained from instrumented Charpy impact test. Two fracture mechanics parameters are dynamic fracture toughness (Jd) and material tearing modulus (T,,,,,). Jd is fracture resistance at crack initia

Instrumented impact testing has been used to study castor-oil-based polyurethanes. The energy-absorbed capacity of these materials in impact is dependent on several factors, such as the type of isocyanate, NCO/OH ratio, and testing temperature. An approximate but simple method for the low-temperatur
