poisson ratio = 0.2f = B/3 *I1 +sqrt(J2)-HpwhereI1 = (xx+yy+zz)J2 = (((xx-yy)**2+(xx-zz)**2-(yy-zz)**2+6*xy**2+6*yz**2+6*xz**2)/6)B = 0.167617820087Hp = 10.4295532498similarlypoisson ration v = 0.2youngs modulus E= 30000sigma (n+1) = C(epsilon(n+1) -epsilonPl(n+1)epsilonPl(n+1) = epsilonPL(n) + deltagamma * derivative of function (f).the conditions aredeltagamma >= 0F(sigma n+1) = 0 (condition plastic)whereC = fourth order tensorepsilon (n+1) = total strainepsilonPL(n+1) = plastic strainBy using this condition I would like to know the values of1) deltagamma how it is determined2) epsilonPL(n+1)3) sigma (n+1)you can assume first as a trialstate and give the value for strainyou have to useepsilon(n+1) as given first notation of this tensor strain epsilon as epsilonxx = 20/300004) than i need to plot the graph of stress vs strain with loading and onloading.5) i need to know all the discription in detain with simple writing .6) all the notation are tensor and vector7) you have to use Newtonraphson to solve this problem
