WebbWhere is the thermal component at 0 K and is the temperature at which the thermal energy is sufficient to overcome the obstacles causing stress, i.e. the temperature at the transition from 1 to 2. The above equation has been verified experimentally. WebbThis is accomplished by solving the governing equations that describe the stress and strain fields (theoretical stress analysis). It is often advan-tageous, where the shape of the structure or conditions of loading preclude a theoretical solution or where verification is required, to apply the laboratory techniques of experimental stress analysis.
