Force and strain relationship
WebMar 21, 2024 · The answer is strain. Suppose the length of a structure with length L undergoes deformation under stress and its length changes to L’, then its change in length ΔL = L’ – L, and the strain ε is the ratio of the change in length ΔL to the original length L, the formula is as follows: So, what is the unit of strain? WebThe Relationship Between Stress and Strain From equation 2, we see that if the shear rate is constant, then the shear stress is zero, even under changing viscosity. It is also true that there are fluids where the viscosity remains constant irrespective of the shear force for constant temperature.
