采用粒子成像测速技术进行颗粒体的形变测量

The paper presents results of strain measurements in cohesionless sand in two different
boundary value problems, namely quasi-static pull-out test of a steel wall and
confined granular flow in a rectangular model silo using a non-destructive method
called Particle Image Velocimetry (PIV) which is a technique for measuring surface
displacements from digital images. Advantages and disadvantages of the method are
outlined. 德国LaVision PIV/PLIF粒子成像测速场仪 材料应变形变成像测量仪 便携式应变形变测量系统
