Consider a Maxwell model (elastic modulus G and viscosity n) connected in parallel with a spring (elastic modulus G2). Derive the constitutive relation between the stress and strain (alongwith their time derivatives) for this three element viscoelastic model. Sketch the stress relaxation curve after step strain clearly indicating the long time behaviour. [5]
