EFFECT OF FLEXIBILITY ON LOW VELOCITY IMPACT RESPONSE
Journal of Sound and Vibration, 1998The 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, 1999Summary: 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, 2017Abstract 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

Low-velocity impact of sandwich composite plates
Experimental Mechanics, 2004In 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 ...

Low-velocity impact on cylindrically curved bilayers
Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2018In 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, 1995Abstract 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.

Low Velocity Impact, Vehicular Damage and Passenger Injury
CRANIO®, 1998Low velocity motor vehicle accidents are a source of injury to many people every year, but the existence of these injuries is often challenged in the courts. The question raised is: "If the vehicle did not suffer any damage, how could the occupant become injured?" This paper reviews the pertinent literature and explains the mechanism of injury.

Low Velocity Impact on Fiber Reinforced Geocomposites
Applied Mechanics and Materials, 2016Low velocity impact strength of the fabric reinforced geocomposite has investigated in this article. Various fabrics such as carbon and E-glass were considered for reinforcement in geopolymer matrix. The primary two parameters such as low velocity, impact damage modes are explained on the E-glass and carbon based fabric geocomposite.
