Question

b. In order to write the differential equation that governs the behavior represented by the Maxwell model, i. What parameter is considered constant, the stress or the strain? i. What assumption is made to get the differential equation that describes this model? (Think about which parameter is added, stress or the strain) Write the differential equation corresponding to the Maxwell model and identify the term corresponding to the spring and to the dashpot. Write the equation for the stress predicted by this model. c. d.

Answer 1

solution
Solution In Manwell model dashpot in serier conciete of spring and 9 rection s 9 The 2 featment of model. - In the dashpot element the Strees will be same as stress in Spring element with the equilibrium require. -ments of tensile specimen which is consistent. the & Total Strain which i equal to straine Summation in each element - & d t Es = e.
