Final answer:
SW stress analysis predicts the material factor of safety by comparing a failure criterion to the tensile strength of the material. Tensile strength is the maximum stress that a material can withstand before it experiences permanent deformation or failure.
Step-by-step explanation:
In SW stress analysis, the material factor of safety is predicted by comparing a failure criterion to the tensile strength of the material.
Tensile strength is the maximum stress that a material can withstand before it experiences permanent deformation or failure. It is an important property to consider in structural analysis to ensure that the material can safely handle the applied loads.
For example, if the failure criterion for a particular material is set at 80% of its tensile strength, then the factor of safety would be the ratio between the actual stress in the structure and 80% of the tensile strength of the material. A factor of safety greater than 1 indicates that the structure is able to withstand the applied loads without failure.
