21. *" Plasticity " or plastic deformation is the opposite of elastic deformation and is defined as unrecoverable strain. 22. This works due to the principle of the inclined plane and the spring force of the elastic deformation of the device. 23. This solution is not accurate for the cases when the elastic deformation of the surfaces contributes considerably to the film thickness. 24. As the names imply, elastics tend to undergo quite a bit of elastic deformation and plastics a lot of plastic deformation. 25. {{ hidden information | title = Proof | info = Elastic deformation in case of a male-female cylinders contact. 26. More recently, Carter, Chachoua, and Chamel ( 2005 ) have formulated a relativistic theory of elastic deformations in neutron stars. 27. When a material is plastically deformed there is no longer a linear relationship between stress and strain as there is for elastic deformations . 28. Also modern linkages appear to have some range of elastic deformation , meaning that they have states between totally taut and totally slack. 29. Tube Hydroformed sections by the nature of their closed sections are very rigid and do not display high degrees of elastic deformation under load. 30. The reason for the elastic deformation of bone is the peak forces caused by muscles ( e . g . measurable using mechanography ).
