Chapter 6 Introduction to strain energy

6.1 Strain energy resulting from direct stress and pure shear stress

6.1.1 Strain energy from direct stress

A typical example of strain energy in an elastic material resulting from a direct stress occurs, for example, when a spring is compressed or extended. The work done on the spring during the compression/extension is equal to the energy stored in the coils of the spring. Since, in the case of a spring, the load required at any instant during the compression/extension is directly proportional to the amount of strain produced on the spring, this may be represented by a straight-line load–extension graph. ...
