Analysis of low velocity frontal impacts
Clinical Biomechanics, 2003The objectives of the study were to determine the phasic recruitment of cervical muscles with increasing magnitudes of low velocity frontal impacts, and to determine quantitative effects of awareness of impending impact in comparison to being impacted unawares.Biomechanics of low velocity frontal impact is poorly understood and requires more work.Ten ...

Metallic dust collectors for low velocity impacts
Advances in Space Research, 1986Experiments simulating the non-destructive collection of cosmic dust are conducted at the laboratory of the Lehrstuhl fur Raumfahrttechnik (LRT) of the Technische Universitat Munchen (TUM). The electromagnetic accelerator setup is described, which is capable of obtaining an impact velocity between 10 and 400 m/s with particle masses up to 1 g.

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.

Low velocity impact response of laminated plates
23rd Structures, Structural Dynamics and Materials Conference, 1982An analysis is presented to predict the response of anisotropic laminated plates to low-velocity impact by a rigid object. Transverse shear deformation in the plates is accounted for using Mindlin's theory and the governing equations are solved using Fourier integral transforms, assuming infinite planform dimensions for the plate.

Low-velocity impact behavior of fiber metal laminates
Journal of Composite Materials, 2011The low-velocity impact response of a range of fiber metal laminate (FML) panels was investigated through testing and finite element simulations. The objective of this study was to understand the impact-damage resistance of these novel composites, so that they can be designed optimally for impact-resistant aircraft applications.

Instrumentation of low velocity impact facility
2017 International Conference on Computing Methodologies and Communication (ICCMC), 2017Our solar system can be mainly defined as a system of objects orbiting around Sun. Among these are mainly Planets and their moon after them we have asteroid and Kuiper belt other than them there are objects with elliptical orbits with high eccentricity or not bound to Sun at all. These objects are smaller in size and comets come into this class.

LOW-VELOCITY PROJECTILE IMPACT ON SPACECRAFT
Acta Astronautica, 2000Abstract Various impact phenomena are encountered in space, among which debris impacts are of most concern. In terms of velocity range of the impacts, structural hazard at very large velocity of over a few km/s is much investigated. However, lower velocity impacts can also be encountered, with similar fatal effects to spacecraft.
