EFFECT OF FLEXIBILITY ON LOW VELOCITY IMPACT RESPONSE

Journal of Sound and Vibration, 1998
The nature of the response of compact and flexible bodies subject to low velocity impact is studied. The key parameters which govern the response for such impacts are identified and their effects on impact response are examined through numerical simulations.

Adaptive computation of impact force under low velocity impact

Computers & Structures, 1999
Summary: We present an adaptive finite element method for evaluation of contact forces under low velocity impact. We consider the contact of spherical and cylindrical impactors with isotropic plates. Adaptive mesh refinement enables the finite element mesh to be obtained automatically, and the refined meshes influence the calculated contact forces ...

Low-velocity impact to transmission line conductors

International Journal of Impact Engineering, 2017
Abstract This combined experimental and numerical study addresses mechanical effects associated with the energy dissipation from transverse low-velocity impacts on a novel High Temperature Low Sag (HTLS) transmission line conductor, subjected to either free or constrained end conditions and large axial tensile loads. Impact experiments were conducted

A review on low velocity impact study of hybrid polymer composites

, 2021
Fibre reinforced composites are rapidly gaining popularity in structural applications but lack of toughness limits their further growth. Fibre hybridization can be considered as a solution for toughening the composite materials which in turn increases ...

Low-velocity impact of sandwich composite plates

Experimental Mechanics, 2004
In this paper we investigate impact and compression after impact properties of plain weave carbon fiber sandwich composites. Impact tests were conducted on different sample types to obtain information about absorbed energy and maximum impact force. The different samples consisted of foam-filled and hollow honeycomb cores with four-layer carbon fiber ...

Damage and failure mechanism of thin composite laminates under low-velocity impact and compression-after-impact loading conditions

Composites Part B: Engineering, 2019
Impact resistance and damage tolerance are of great significance in the design of composite structures. This study investigated the damage and failure mechanism of thin composite laminates under low-velocity impact and compression-after-impact (CAI ...

Low-velocity impact on cylindrically curved bilayers

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2018
In this study, low-velocity impact response of cylindrically curved bilayer panels is studied. A large number of parameters affect the impact dynamics and many models have been used for solution previously. These models can be classified as energy balance model, spring–mass model, and complete models in which the dynamic behavior of the structure is ...

Instrumented low-velocity impact of CFRP beams

International Journal of Impact Engineering, 1995
Abstract Low velocity impact of carbon fiber reinforced epoxy (AS4/3502 by Hercules) was conducted with 48 and 40 layered beams of different combinations of 0°, 90°, 45° and −45° stacking sequences. The test set-up included an instrumented drop weight and data acquisition system.
