Low-velocity impact strength of sandwich materials
Journal of Sandwich Structures & Materials, 2010Sandwich materials have been widely used in weight-sensitive structures in many fields, especially in the transport industry. There are different classes of sandwiches with a wide range of materials and properties within each type. The aim of this article is the comparison of the impact strength between polymeric and aluminum sandwich structures ...

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.

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.

Sports Engineering, 2007
There has been significant technological advancement in the game of tennis over the past two decades. In particular, tennis rackets have changed in size, shape and material composition. The effects of these changes on ball rebound speed have been well documented, but few studies have considered the effects on ball angular velocity.

Tribology at high-velocity impact
Tribology International, 2007Abstract The tribological events taking place when a high-velocity projectile hits a SiC particulate reinforced AA 5083 composite material was examined under real conditions. The samples were cast in a disc shape by squeeze casting method. Different volume fractions of SiC particles were used.

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.

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 ...

Impact Crater Formation at Intermediate Velocities
Journal of Basic Engineering, 1972The influence of projectile strength on cratering was investigated for projectiles of aluminum alloys impacting semi-infinite aluminum targets over the velocity range of 1 km/sec to 5.0 km/sec. The experimental results showed that crater diameters were not significantly influenced by varying projectile strength.

Limit Impact Velocity of Frangible Bullet
2019 International Conference on Military Technologies (ICMT), 2019The article deals with the determination of a limit impact velocity of a frangible bullet. Limit impact velocity is the lower limit impact velocity of the bullet on the hard target, at which the bullet begins to shatter into the fragments. The limit impact velocity of the bullet is one of the criteria to evaluate the frangibility of the frangible ...

Damage threshold velocities for liquid impact
Journal of Materials Science, 2000Rain erosion is a major cause of strength and transmission loss in IR ‘windows’ in high velocity flight. The Cavendish Laboratory's Multiple Impact Jet Apparatus (MIJA) is able to simulate high velocity rain impact accurately and reproducibly under laboratory conditions using a series of discrete water jets.
