Over the decades, ASTM shear test methods have continued to evolve as composite applications require higher shear strengths.
The offset shear strength is the shear stress endured by a material at the intersection of the shear stress versus the engineering shear strain curve, with a line parallel to a defined modulus and ...
It is possible to characterize the shear thinning behavior of thermoplastic materials using a Flow Rate Ratio (FRR) test method in an extrusion plastometer (melt indexer). This test method, “Procedure ...
