The analysis of composite laminated beams using a 2D interpolating meshless technique

摘要

Laminated composite materials are widely imple-mented in several engineering constructions.For its relative light weight,these materials are suitable for aerospace,mil-itary, marine, and automotive structural applications. To obtain safe and economical structures,the modelling analysis accuracy is highly relevant.Since meshless methods in the recent years achieved a remarkable progress in computational mechanics,the present work uses one of the most flexible and stable interpolation meshless technique available in the literature—the Radial Point Interpolation Method(RPIM). Here, a 2D approach is considered to numerically analyse composite laminated beams.Both the meshless formulation and the equilibrium equations ruling the studied physical phe-nomenon are presented with detail.Several benchmark beam examples are studied and the results are compared with exact solutions available in the literature and the results obtained from a commercial finite element software.The results show the efficiency and accuracy of the proposed numeric tech-nique.
