多轴测试

需要进行更逼真的多轴测试

当无法仅通过单轴测试预测材料或组件断裂时，使用多轴或多模测试可以模拟更加逼真的实际使用条件。 Testing is performed under axial-torsion,  planar-biaxial or axial-shear loading, to more complex three and four axis loading that includes torsion, bending, shear and pulsatile forces to address the nuances of combined states-of-stress that are typically seen in real life conditions.  Multiaxial testing is often performed as the final test scenario for critical use situations in medical, auto and aerospace applications.

Multiaxial testing also serves to validate finite element modeling often created from uniaxial material test data.  Oftentimes, modeling alone cannot predict the true interaction of material behavior if it relies solely on simple uniaxial material mechanical properties.  Additionally, many regulatory entities responsible for the safety and efficacy of products, such as the medical and transportation industries, have stringent expectations to perform such multiaxial tests.

功能丰富，适用于各种应用

ElectroForce test instruments are configurable to meet many specific multiaxial testing needs.  Whether it is to perform  biaxial tests of pericardium, or to understand the biomechanics of spinal disk implants and peripheral stents, or to evaluate the tribological properties of dental materials, ElectroForce instruments provide a versatile alternative to traditional technologies.

其他应用包括评估骨科所用骨螺钉的旋入扭矩和切削性能，或评估负载和扭矩极低的颌鼻甲骨测试应用。
