Problem 3 (10 pts). When using linear shape functions to solve the multiphysics thermo- elastic problem considered in class, we found that the stress in the rod is affected by unphys- ical oscillations like the following plot E*(ux-a*T) 35000 30000 25000 20000 15000 10000 5000 0 -5000 H -10000 Line Graph: E*(ux-a*T) MULTIPHU 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 Arc length (a) [10pts] What is the origin of this issue and how can we fix it?

i want a displacement and stress equations and mak calculation

Don't copy ,Please provide Diagram and Equation as a part of explanation with correct Final answer. [ Try within 30-45minutes]

Calculate the stiffness matrix for the Q8 element shown below. Make use of the shape functions in natural coordinates and the Jacobian calculated in previous problems. Use 2x2 Gaussian numerical integration. Use plane strain conditions (for unit thickness) with E=200E9 (MPa) and nu=0.25. The final answers is F1= 0.18452e12. I have attached my matlab code below. Please look thru it and correct it.

the question is in the picture

I need only MATLAB coding please.....
