Stresses around polygonal hole in an infinite laminated composite plate

• A generalized solution is presented for an infinite composite plate with polygonal holes.
• Muskhelishvili's complex variable approach is adopted.
• The effect of loading factor and stacking sequence on stress pattern is studied.
• The effect of material parameters, hole geometry and fiber orientation is also presented.

A General solution for determining the stress field around polygonal hole in a laminated composite infinite plate subjected to arbitrary biaxial loading, with layers of arbitrary fiber orientations and stacking sequence, is obtained using complex variable approach. The effect of material parameters, hole geometry, fiber orientation angle and loading pattern, on stress field around hole is studied.
