Abstract: |
Based on the classical composite laminate theory,a finite composite plate weakened by multiple elliptical holes is treated as an anisotropic plate.Using the Faber series method in complex theory combined with the least squares boundary collocation techniques on the finite boundaries,the bending problem of a finite composite plate weakened by elliptical rigid inclusions is studied by means of the complex variable method.As a result,concise and high accuracy solutions are presented for the stress distribution around the rigid inclusions.Finally,numerical examples are presented to discuss the effects of some parameters on the stress concentration around the rigid inclusions.The results showed that the present method is not only very efficient for analysis of the stress distribution of finite laminates with multiple elliptical rigid inclusions,but also is highly accurate and needs short computer time. |
