Combination experimental and theoretical method for determining the stress state of structural elements with cracks
- 25 Downloads
We propose a combination experimental and theoretical method for determining the stress state of sheet structural elements with cracks. The method involves estimating the load (the stress) acting on the structural element with a crack, using the experimentally measured displacement of the crack surfaces caused by action of that load. To do this, we use fracture mechanics equations connecting the indicated parameters. As an example, we solve several problems for plates of finite dimensions with cracks for two load application methods.
