Mechanical properties and testing of polymers
WebShear tests are used to determine such attributes as shear strain, shear stress and shear modulus, report the stress, strain, modulus and failure mode (if applicable), as awareness of the ‘deformable’ mechanical properties of plastics, composites and other samples is … WebMechanical testing is an essential and standard part of design and manufacturing that determines the mechanical properties of a material or final product. Testing should occur under the given environmental conditions associated with service. Tests can either provide material evaluations at defined geometries or at a base material properties level.
