The stress testing based on counter magnetostriction effect of ferromagnetic materials is a new technique. 摘要基于铁磁材料压磁效应的应力测量是一种新技术。
When strain waves pass through a ferromagnetic bar,owing to piezomagnetic effect,a nonuniform magnetic current will be stimulated by the strain wave simultaneously. 应变波通过铁磁性杆件时，由于压磁效应，会同时在杆件中激发出不均匀的磁流。
