Planar Biaxial Testing

Components made from metals, alloys and composites are often subjected to complex multiaxial stresses during service. Planar biaxial testing generates more accurate simulations of real-world stress states. Essentially, planar biaxial testing provides a method for investigating in-plane stress states of materials or biaxial loading of design elements, such as the mechanical joint or interface of a component. Specimens are typically cruciform. Tests may involve both tension and low-cycle fatigue, with forces ranging from 25 to 500 kN (5,500 to 110,000 lbf), as well as thermal environments for high-temperature testing.
