EXAMPLE 3.9
Finite-element²¹ analysis shows that a long structural component car-
ries a uniform axial stress of 35 MPa (T) (Figure 3.29). A hole in the
center needs to be drilled for passing cables through the structural
component. The yield stress of the material is 200 MPa. If failure due
to yielding is to be avoided, determine the maximum diameter of the
hole that can be drilled using a factor of safety of 1.6.

- For a given homogeneous, isotropic, linearly elastic material, E = 15e6 psi and v = 0.3. Solve for the shear modulus. 2.1.1 Homogeneous, isotropic, linearly elastic materials For specimens undergoing small deformations, the stress-strain diagram often ex- hibits a linear behavior. Although this is a very crude approximation to the behavior of actual materials, it is a convenient assumption that is often used for preliminary evaluation. A linear relationship between stress and strain can be expressed as 01 = E €1, (2.1) where the coefficient of proportionality, E, is called Young's modulus or modulus of elasticity. Since strains are non-dimensional quantities, this coefficient has the same units as stress quantities, i.e., Pa. This linear relationship is known as Hooke's law. The elongation of a bar in the direction of the applied stress is accompanied by a lateral contraction that is also proportional to the applied stress.
