Calculate a steel plate with a yield strength of 215 MPa and a thickness of 2 mm. How should the pressure at the limit of deformation under compression be calculated?

The thickness is 2 mm, and the length, width, and height are 100–20–100. How should this be calculated? What is the maximum pressure at which it can remain undformed? Or which book covers calculations in this area?
Pressing two thick ones with your hand will cause them to deform.
A rectangular container without reinforcement has very little load-bearing capacity and tends to deform significantly
First of all, the absence of plastic deformation means no deformation at all. Secondly, this can be transformed into solving a static pressure problem. Moreover, the ultimate stress that can be withstood is highly dependent on the manufacturing process; if it is a purely square shape, the load-bearing capacity is limited due to stress concentration at the joints.
