Discover The Answers ™ Mechanical Testing of Plastic, Rubber, Elastomer, and Composite Materials By Steven Tysoe Ph. D. and Jim Zwynenburg Associated Polymer Labs (APL) adds another electromechanical Universal Testing Machine (UTM) to the Mechanical Properties Testing Laboratory. The new Shimadzu AGS-X 500mm extended frame UTM is perfect for testing polymeric materials including plastics, rubbers, elastomers, and composites. The Shimadzu AGS-X 10kN load frame with Trapezium Control Software allows the operator to stretch (tensile), bend (flexural), compress or squash (compression), or pull (shear) a specimen until it moves, yields or to the breaking point. Tensile testing is performed in accordance with American Society for Testing and Materials (ASTM) Methods D882, D638, D412, D1708 and other custom test methods designed to meet your requirements and needs. Tensile properties are key indicators of the strength of a material. Results from tensile testing include the yield point, tensile (Young’s) modulus, tensile strength, elongation, break point, and toughness. Flexural testing is performed in accordance with ASTM Method D790 to measure the flexural modulus. Many brittle materials are flexed to the breaking point in order to measure the flexural strength. The test is stopped when the specimen reaches 5% deflection or the specimen breaks before 5% deflection is reached. The flexural test measures the force required to bend a beam at a specific rate. Flexural modulus is an indication of a material’s stiffness when bent on a three-point apparatus. The three point bending fixture supports the specimen a
