Stress analysis is used to determine the different stresses produced in an object when it is subjected to various external forces (pressures, accelerations, temperatures) and the contact between components. Materials need to be determined before stress analysis can be performed, as the material will very likely change the outcome of the analysis.
Using data from the dynamic simulation of the product, stress testing can be performed in order to determine the material combinations appropriate for the amounts of stress being applied to the device at any given time. This allows our engineers to ensure a part is not over or under-engineered. Stress testing is achieved by applying real-world stresses to a part and analyzing the stresses acting on the part assembly as a whole. Our engineers can then determine whether the part can withstand the specified stresses without failing and go on optimizing the design to reduce cost and complexity.
In stress testing there are several subsets of analysis:
- • linear analysis,
- • non-linear analysis,
- • mechanical event simulation,
- • fatigue (or cycle) testing, and
- • thermal testing.
The applications of stress testing include:
- • industrial design,
- • aerospace,
- • mechanical,
- • commercial,
- • dental modeling, and
- • medical modeling.
