Abstract

Purpose

Due to the important and extensive use of graphene in the engineering structures, the purpose of this paper is to investigate the low-velocity impact (LVI) response of a graphene-reinforced plate with a rectangular central hole.

Design/methodology/approach

In this paper, Halpin-Tsai theory is used to model the mechanical properties of the plate made of polymethyl methacrylate (PMMA) resin and graphene particles. First, the plate displacement field is presented, and then the strains and stresses are obtained. The motion equations are extracted using energy equations, Ritz method and generalized Lagrange equations. The verification of theoretical formulation shall be carried out using the ABAQUS finite element software suite.

Findings

The effects of graphene volume fraction, approaching the impact point to the corner of the rectangular plate, and different boundary conditions of the plate are studied for LVI of impactor with spherical tip on the rectangular central hole reinforced by graphene. Important responses of the impact, such as the contact force between the impactor and the plate as well as the displacement of the plate at the impact place, are investigated and analyzed in this research.

Originality/value

Considering the wide application of graphene in the engineering structures, the simulation of the LVI on the graphene-reinforced plate made of PMMA resin with a rectangular central hole is carried out in this paper using numerical and theoretical modeling.

由 PMMA 树脂制成、含有中心矩形孔并使用石墨烯颗粒增强的平板：低速冲击分析

鉴于石墨烯在工程结构中的重要而广泛的应用，本文旨在研究具有矩形中心孔的石墨烯增强板的低速冲击（LVI）响应。本文采用 Halpin-Tsai 理论建立了由聚甲基丙烯酸甲酯（PMMA）树脂和石墨烯颗粒制成的板的力学性能模型。首先给出板的位移场，然后求出应变和应力。利用能量方程、里兹法和广义拉格朗日方程提取运动方程。研究结果研究了石墨烯体积分数、撞击点接近矩形板角以及板的不同边界条件对球形顶端撞击器对石墨烯加固的矩形中心孔的 LVI 的影响。考虑到石墨烯在工程结构中的广泛应用，本文利用数值和理论模型模拟了石墨烯对由 PMMA 树脂制成的矩形中心孔石墨烯增强板的 LVI。
