Rigid plates are plates that deform very little when subjected to force, while elastic plates deform significantly when subjected to force. Below is a detailed explanation of the two:
Rigid Plate: Definition: Rigid plates are plates that undergo almost no deformation under external force. While completely undeformable materials do not exist in reality, rigid plates are materials that undergo only minimal elastic deformation even under external force.
Characteristics: Rigid plates have strong resistance to deformation, and even under large external forces, their deformation remains relatively small.
Elastic Plate: Definition: Elastic plates are plates that deform under external force, but this deformation can partially or completely recover after the force is removed. Deformation Classification: Deformation of elastic plates can be divided into elastic and plastic deformation.
Elastic deformation refers to deformation that can be fully recovered after the force is removed, while plastic deformation refers to deformation that cannot be recovered after the force is removed. Elastic Limit: Elastic plates initially deform elastically under external force, but when the external force exceeds a certain limit, plastic deformation occurs. The better the elasticity of the material, the greater the elastic limit, and vice versa.
