Using results from Exercises 3.19 and 8.43, show that the mode I crack tip von Mises stress
Question:
Using results from Exercises 3.19 and 8.43, show that the mode I crack tip von Mises stress is given by:
Next solve this equation for the radial coordinate and make a polar plot for a typical von Mises stress contour (σe = constant) about the crack tip. Result should look like the following figure, and represents the shape of the plastic zone size for the plane stress mode I crack problem.
Data from exercise 3.19
For the two-dimensional plane stress case (see Exercise 3.5), show that the relationship between the maximum shear stress and von Mises stress is given by:
Equation 8.43
