Evaluation of Compression Strength After Low Velocity Impact

American Society for Composites 2018, 2018
Damage due to impacts is a large concern for composites use in the aerospace industry. Low Velocity Impact (LVI) damage can significantly reduce the in-plane strength of laminated composites, and understanding how they behave after such damage occurs is important for predicting the failure of these composites.

Impact and compression after impact behavior of single-stiffener composite panels

2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017
The purpose of this paper was to investigate the damage tolerance of single-stiffener panels. The impact response and the influence of impact damage on compression behavior were studied. Barely visible impact damage (BVID) was introduced to the stiffener flange tip on the smooth side. By applications of visual inspections and C-scan, massive damage was

SIMULIA Abaqus Simulations to Predict Compression-after- impact Behavior

American Society for Composites 2019, 2019
Fiber-reinforced composites are receiving increased attention due to their superior mechanical properties compared to traditional materials. Since composites are made of multiple components, their failure mechanisms are complex and involve competing failure modes.

Compression Strength of Stitched Laminates after Low-velocity Impact

Journal of Reinforced Plastics and Composites, 2005
Tests are conducted using stitched laminates in order to calculate the unnotched failure stress and the compression after impact (CAI) strength of the stitched laminates. Unnotched laminates, laminates with a hole, and laminates with impact damage are used in the tests.

Compression-after-impact response of woven fiber-reinforced composites

Composites Science and Technology, 2010
This manuscript investigates compression-after-impact failure in woven fiber-reinforced composites. Compression failure of composite structures previously damaged by an impact event is due to the propagation of impact-induced damage mechanisms such as interlaminar debonding, constituent (i.e., matrix and fiber) microcracking, sublaminate buckling, as ...

Predicting Compression-After-Impact Strength of Composite Sandwich Structures

49th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference <br> 16th AIAA/ASME/AHS Adaptive Structures Conference<br> 10t, 2008
In order to gain a better understanding of the damage tolerance properties of a composite sandwich structure, a computational Progressive Failure Methodology (PFM) was incorporated into a finite element model representing a Compression-After-Impact (CAI) test.

Simulation of edge impact and compression after edge impact in CFRP laminates

Composite Structures, 2020
Abstract This paper presents the application of a composite damage model to predict the edge impact and compression after edge impact (CAEI) response of CFRP laminates. First, a mesh sensitivity analysis is performed showing that the mesh needs to be sufficiently fine to accurately capture the permanent out-of-plane deformation at the impact location,

Compression After Impact Modeling of Damage Tolerant Composite Laminates

51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 18th AIAA/ASME/AHS Adaptive Structures Conference<BR> 12th, 2010
An existing compression after impact (CAI) model was used as the fitness function in an optimization routine to produce a damage tolerance optimized composite layup. This laminate was tested in a CAI strength experiment, alongside a baseline quasi-isotropic layup.
