Deformation

• What is deformation?


  Deformation is a change in the shape of an object caused by stretching, squashing (compressing), bending, or twisting
• What is required to deform a stationary object?

  More than one force has to act on a stationary object to deform it; otherwise, the force would make it move
• What is elastic deformation?

  Elastic deformation occurs when an object can go back to its original shape and size when the deforming forces are removed
• What is inelastic deformation?

  Inelastic deformation occurs when an object does not go back to its original shape or size when the deforming forces are removed
