An Explicit Dynamics Solution for Low-Velocity Impact of Composite Plate Structures against Various Boundary Conditions Using Abaqus

Abstract:

Nowadays to examine the simulation analysis of low-velocity impact impairment on composite structure to increase the impact force by using various velocities of the impactor with different boundary conditions. These composite structures are progressively used in aerospace predominant parts. In this paper, the Carbon/epoxy composite plate subjected to low-velocity impact loading of the laminate is studied. This composite structure is widely used in automobile, aerospace, marine, and construction fields due to its admirable mechanical and physical properties compared to metal structures. To ascertain intralaminar impairment commence and growth by using Hashin’s damage criterion. The simulation study was performed using ABAQUS CAE/explicit based on a modified continuous impair pattern to examine the dynamic mechanical response and damage evolution in various orientations of integrated laminate subjected to low-velocity impact. The low-velocity impact analysis has been run to understand the reaction of composite laminate by low-velocity impact. The stacking sequence of the composite structure is [0₂/+45₂/+90₂/-45₂]_s to analyze the impact force-time curve. The simulation study brought maximum impact force using impactor velocities varying from 2.5 meters/sec to 7.5 meters/sec with different boundary conditions CCCC, SSSS, SSCC, and CCSS. These boundary conditions are major changes that occur and impact force-time curve.
