Definition

The boundary element method (BEM) is a numerical technique to solve engineering/physical problems formulated in terms of boundary integral equations. Composite laminates are assemblages of stacked different materials layers, generally consisting of variously oriented fibrous composite materials.

Generalized Plane Strain Problem

Let us consider an anisotropic, cylindrical, elastic body having cross section Ω with boundary Γ. The body is referred to the coordinate system xyz with the z-axis directed as the cylinder generatrices.

Governing Equations

Under the hypothesis of generalized plain strain ( ε zz = 0), the elastic state of the body is described in terms of the displacement vector \(\boldsymbol {u}= \begin {Bmatrix} u_x & u_y & u_z \end {Bmatrix}^T\)
