For the stress state in Exercise 3.8, plot contours of the von Mises stress in the region
Question:
For the stress state in Exercise 3.8, plot contours of the von Mises stress in the region 0≤x ≤L, –c≤ y≤ c, with L = 1, c = 0.1, and P = 1.
Data from exercise 3.8
Exercise 8.2 provides the plane stress (see Exercise 3.5) solution for a cantilever beam of unit thickness, with depth 2c, and carrying an end load of P with stresses given by:
Data from exercise 8.2
Show that the Airy function:
solves the following cantilever beam problem, as shown in the following figure. As usual for such problems, boundary conditions at the ends (x = 0 and L) should be formulated only in terms of the resultant force system, while at y =± c the exact pointwise specification should be used. For the case with N = 0, compare the elasticity stress field with the corresponding results from strength of materials theory.
Data from exercise 3.5
A two-dimensional state of plane stress in the x, y-plane is defined by σz = τyz = τ zx = 0. Using general principal value theory, show that for this case the in-plane principal stresses and maximum shear stress are given by:
