Biaxial testing machine LFV

During service components are often subjected to multiaxial stresses. For biaxial testing of materials, particularly composites, metals, textiles, biomaterials or plastic under a wide range of biaxial stress states, typically a cruciform specimen in conjunction with a testing machine capable of bearing independently controlled loading on two orthogonal axes is used. The cruciform specimen avoids stress concentrations and provide a uniformly stressed test section. Load application for the cruciform can be accomplished in a robust frame supplied with a separate drives (either electromechanical or servohydraulic) and separate load cell to check for off-axis or unbalanced loading. Depending on test conditions w+b offers Biaxial Testing Systems in different configurations adapted to multiaxial testing in creep, static strength, fatigue or high speed mode in different force ranges.
