Question 9 3 pts A polymer has creep behaviour that can be represented as a power law equation: where Jo is 0.5 GPa¹, J₁ is 0.45 GPa 10.3 and n is 0.3 (with t in seconds). A component of this material has the following applied stress history: There is no stress before t = 0 A positive (tensile) stress of 12 MPa is applied from t = 0 for 4 hours From t = 4 hours to 7 hours, the stress is compressive stress of 2 MPa The stress is then removed. What will the strain in the material be at t = 9 hours? Enter your value as a number to 4 decimal places. You have a 2% error margin with this.
