WebThe length increases, the object turns thinner and longer. This is called tensile strain. By applying compressive stress, when an object is compressed, there is some force acting up against it which helps in deformation. This is called compressive strain. Shearing forces/stress cause deformation. 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 …

Some tendons have a high collagen content so there is relatively little strain, or length change; others, like support tendons (as in the leg) can change length up to 10%. Note that this stress-strain curve is nonlinear, since the slope of the line changes in different regions.
