纤维增强复合材料试验研究的数值模拟

摘要

Although the FRP has has been abundantly studied at home and abroad, there are many uncertain factors in practical projects. suffered from composition, processing technique, bonding methods and other influence factors, deformation, deflection change and failure mode of composite materials are not consistent with different shape and force of materials. This paper conducted indoor experiment and numerical simulation to H-shaped GFRP beam, and studied the mechanical properties and failure form.%国内外对于FRP虽然已经进行了大量的研究工作,但是在实际工程中仍然会出现很多不确定的因素.复合材料由于受组成成分、生产工艺、粘合方式等因素影响,不同形状的材料和受力情况,复合材料的变形、挠度变化和破坏方式是不一致的.本文对工字型GFRP梁进行室内实验和数值模拟,对GFRP梁的受力性能和破坏形态进行了研究.
