Compliance Functions for Through-Thickness Measurement: The FEM Approach
- 1.1k Downloads
Many configurations which require residual stress measurement differ from those we discussed in the previous chapter and do not have analytical solutions available from fracture mechanics. In this case we can use the finite element method (FEM)  to obtain numerically the crack compliance functions for a specimen of a complex geometry. Since this approach allows the compliance functions to be obtained for a crack as well as a slit of finite width,in what follows,we will use the term “compliance functions” interchangeably for a crack and a slot.
