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 ...

President, Wyoming Test Fixtures Inc. The test fixtures and specimens used for the three methods are compared in Fig. 1, at left. All three apply an asymmetrical four-point bend loading to the ...

Many complex fluids, such as surfactant mesophases, network forming polymers, emulsions etc. do not flow until the applied stress crosses a certain critical value, called the yield stress. Materials ...
