Description

Papers abstract:

In this paper, the failure response of aluminum sandwich panels subjected to low-velocity impact is discussed. A three-dimensional geometrically correct finite element model of the honeycomb sandwich plate and a rigid impactor was developed using the commercial software, ABAQUS. This discrete modelling approach enabled further understanding of the parameters affecting the initiation and propagation of impact damage. Strain-hardening behavior of the aluminum alloys and the honeycomb core density were shown to affect the impact response. In addition, the impulse–momentum equation was incorporated into the energy-balance model, so that the impact force and deflection histories could be determined as well.

Product Overview:
This tutorial explores the behavior of aluminum honeycomb sandwich structures under high-speed impact, offering a direct application of finite element methods in Abaqus. Building upon the ISI paper’s low-velocity model, this simulation adapts it for more demanding, real-world impact conditions. Key simulation steps include:

  • Creating detailed honeycomb core and face sheet geometries using shell elements
  • Assigning Johnson-Cook material models for high-strain-rate accuracy
  • Setting up dynamic explicit steps and contact interactions
  • Applying realistic impact conditions with projectile velocity and boundary constraints
  • Meshing with deletion-enabled elements for damage tracking.

 

In this tutorial, medium to high-velocity impacts on aluminum honeycomb sandwich panels are simulated, according to data from the work of C.C. Foo et al.

More information

  • This tutorial extends the validated research model by Foo et al. to simulate medium and high-velocity impacts, incorporating Johnson-Cook plasticity and real-time stress visualization. The step-by-step instructions make it accessible for engineers aiming to assess impact tolerance in lightweight composite structures. With editable CAE and INP files included, users can tailor the model to explore various impact conditions, geometries, or materials relevant to aerospace, automotive, or defense applications.
