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.

Low Velocity Impact, Vehicular Damage and Passenger Injury

CRANIO®, 1998
Low 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.

SIMULATIONS OF RESPONSE TO LOW VELOCITY IMPACT BY SPREADSHEET

International Journal of Structural Stability and Dynamics, 2010
A program which can be used to simulate the elastic response of lumped mass single-degree-of-freedom systems to impact actions is introduced in this paper. The underlying governing equations and the implementation of their solutions on a spreadsheet are described.

Low velocity impact properties of flax composites

Composite Structures, 2017
Abstract The investigation of the impact performance of flax-based composites is the key in order to understand which material parameters determine the safety and longevity of flax composite products. In this study, the effect of fibre architectures and matrix type on the absorbed energy after perforation, on the damage resistance as well as on the ...

EFFECTS DUE TO LOW VELOCITY IMPACT IN MECHANICAL OSCILLATORS

International Journal of Bifurcation and Chaos, 1992
Phenomena caused by low velocity impacts in a class of forced impact oscillators are studied. It is shown that such impacts play an important role in the dynamics of general impacting systems. Features observed in numerical simulations of different oscillator models are associated with previous theoretical work on grazing impact.

Low Velocity Impact Testing on Laminated Composites

2021
The response of composite laminates from transverse impact loading is known to vary with the speed of impact. In Low Velocity Impact (LVI) conditions, boundary effects usually dominate since the impact duration is longer between the laminate and the impactor.

The low velocity impact response of sandwich structures

2013
In this study, the mechanical properties and fracture behaviour of a range of core materials have been investigated in order to elucidate the impact properties of sandwich structures. Initially, the compression properties of the core have been evaluated at quasi-static and impact rates of strain.
