WebE = σ ε. The relationship between stress and strain of different materials are given below: From the above graph for a perfectly rigid plastic body, the strain is zero even though stress is applied, so from the equation. E = σ ε. If the strain is zero then young's modulus becomes infinity. ∴ The elastic modulus for the perfectly rigid ... WebGenerally, nobody is perfectly elastic and perfectly plastic; but they are between these two extremes. Normally, quartz is the perfectly elastic body and putty, the wax is perfectly plastic bodies. Rigid bodies: Bodies which do not get deformed or have very small deformation on applying external force are called rigid bodies.
