If you design laminated structures, such as sandwich panels, you might be interested in knowing that the through-the-thickness normal stress, properly disregarded in homogeneous structures, may play a fundamental role in triggering delamination.
I need to know the analytical solution for the stress field in an isotropic infinite plate with a circular inclusion, assuming linear elasticity. The plate has an applied tensile stress.
The solution for a hole in an infinite plate is very common (http://en.wikiversity.org/wiki/Introduction_to_Elasticity/Plate_with_ho…). I need a similar solution in which the inclusion has some elasticity tensor C and the matrix some tensor C_0 with C=x*C_0, where x is a scalar.
Thanks!
