Deformation energy equation
WebJan 25, 2024 · Summary. When a deformable structure, such as a spring, rubber or metal stretches, then it stores a type of energy known as strain energy. Thus the total strain energy \ ( (U),\) for small deformation is … WebNote on terminology: “Fluid deformation” is equivalent to “velocity gradient,” and the two terms can be used interchangeably. They are different ways of thinking about the same concept. Thus, \(G\) is the measure of both terms. \(\varepsilon\), or energy dissipation rate, is the rate that the kinetic energy of the fluid is being converted to heat.
