THERMAL STRESS IN A UNIFORM PLATE
Thermal Stress in a Uniform Plate Calculator has been developed
to calculate stress of a uniform plate (edges fixed) when the temperature of the
plate is uniformly changed.
If the temperature of a plate, whose edges are fixed, is increased by ∆T, the
plate cannot expand due to restraints. The fixed ends exert forces on the plate
to keep it from expansion. Thus, a state of stress is created in the plate. This
thermal stress depends to the temperature change ∆T, coefficient of thermal
expansion (α), elastic modulus (E) and Poisson's ratio (ν) of plate material.
