Thermo-mechanical stress
Did you know?
In mechanics and thermodynamics, thermal stress is mechanical stress created by any change in temperature of a material. These stresses can lead to fracturing or plastic deformation depending on the other variables of heating, which include material types and constraints. Temperature gradients, thermal … Visa mer When a material is rapidly heated or cooled, the surface and internal temperature will have a difference in temperature.
