Abstract |
|
|
| A novel model is presented to determine the inter-laminar stresses near the free edges of composite laminate plates subjected to mechanical loading. The proposed method is based on an admissible function representing inter-laminar stresses which account for the effects of both the global mismatches and the local mismatches in two elastic properties such as poissons ratio and coefficient of mutual influence. For this purpose, new mechanical mismatch terms are defined to reflect an effective deformation on a $0/90/90/0$ cross ply composite laminated structure. It is found that the present approximate method yields inter laminar stress results in an efficient, fast and reliable way. It is observed that unlike some previous approximation methods, the proposed method is numerically robust and stable. For validating the results of the proposed approach, experimental and numerical analysis were performed and presented. |
