다축 실험

보다 현실적인 다축 실험의 필요성

간단한 단축 실험을 통해 재료 또는 성분의 파괴를 예측할 수 없는 경우, 다축 또는 다중 모드 실험을 통해 보다 현실적이고 실제적인 사용 조건을 시뮬레이션할 수 있습니다. 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.

광범위한 응용 분야를 위한 다양한 기능

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.

추가적인 응용 분야로는 정형외과에 사용되는 접골 나사의 절삭 성능 및 삽입 토크의 평가, 하중 및 토크 수준이 매우 낮은 경우가 많은 턱과 얼굴 부위 관련 실험 등이 있습니다.
