Square field.
Background technology
Analysis of Experimental Stress is an important component of deformation mechanics.In Practical Project, it would be desirable to use stress
It analyzes to solve the problems, such as mainly due to following 3 reasons：
1. pair certain test specimens, other than analysis is carried out using existing theoretical formula and is calculated, it is also necessary to pass through the side of experiment
Method verifies result.
2. because theoretical calculation inevitably carries out necessary simplification to the shape of actual components, force-bearing situation, most
Whether whole result tallies with the actual situation and must be verified by testing.
3. for assembly or component that structure is more complicated, want to acquire answer using the mechanics of materials and elastic theory with simple
It is also relatively difficult.Even if using approximate computational methods, the reliability of result of calculation will also be tested by testing
Card.
In Practical Project, the method for current most common measuring stress is with strain gage testing stress.I.e.
