摘要

．复合材料在航空航天、船舶、汽车等各种应用中的使用迅速增加;由于其具有优异的疲劳性能、良好的强度重量比、耐腐蚀性等特点。本文主要研究以环氧树脂为基体的玻璃纤维增强聚合物(GFRP)复合材料，因为它是最常用的高强度和低成本的纤维。采用ANSYS机械APDL软件对具有相同堆叠顺序和8层有分层和无分层的玻璃钢试样进行了数值分析。观察到固有频率随分层参数的变化而变化。

Numerical Investigations on GFRP beam with Delaminations

. Usage of composites have rapidly increased in various applications likeaerospace, marine, automotive; because of their superior fatigue properties, good strength to weight ratio, corrosion resistance, etc. This work focus on Glass fibre Reinforced Polymer (GFRP) composite with epoxy as matrix, as it is the most commonly usedfibre with high strength and low cost. Numerical analysis on GFRP samples with and without delaminations having same stacking sequence and eight layers were done using ANSYS mechanical APDL software. It is observed that Natural Frequencies is varying according to changes in delaminations parameters.
