7. Consider a mixing sequence involving two sequential deformation gradients of F1 and F2. Solve the following problems. a) For an initial interfacial area vector A0, write an expression representing the deformed interfacial area vector after the mixing sequence. (Write your answer in terms of A0,F1 and F2). b) Consider a specific case with F1=cossin0sincos0001 and F2=200010001. What is the deformation gradient tensor at the end of the mixing sequence? (Write your answer in a matrix form in terms of and )
