Structural Impact is concerned with the behaviour of structures and components subjected to large dynamic loads which produce inelastic deformation. This field is of particular interest for the crash-worthiness design of aircraft, buses, cars, trains, ships and marine structures, and the energy absorbing characteristics of various components for a wide

Impact of structure on photogating
Journal of Applied Physics, 1996In previous reports, we predicted with computer simulation that photocarriers from blue bias light can contribute under certain conditions to the quantum efficiency in the red wavelength part of the spectrum for hydrogenated amorphous silicon (a-Si:H) p-i-n and Schottky barrier structures.

SAE Technical Paper Series, 1969
NEW SIDE SAFETY STRUCTURAL CHANGES HAVE BEEN DEVELOPED FOR SOME 1969 MODEL GENERAL MOTORS CARS. THE RESEARCH COVERED TWO YEARS, DURING WHICH TIME CRASH SITUATIONS WERE SIMULATED AND ANALYZED, FIELD DATA WERE STUDIED, AND VARIOUS APPROACHES TO SIDE PROTECTION WERE INVESTIGATED.

On the structure of frictional impacts
Acta Mechanica, 2017Many processes in machines and mechanisms are accompanied by impacts with friction. They arise by short-time contacts between two or more bodies, and they generate energy losses mainly due to friction in tangential contact directions. During the last three decades, a couple of impact models based on the theory of rigid body contacts were established ...

Impact on a head-neck structure
Journal of Biomechanics, 1976Abstract An analytical and experimental study was executed involving non-destructive, axisymmetric impact on a fluid-filled shell constrained by a viscoelastic, artificial neck—a system intended to simulate a human head-neck structure. The shel material was considered to be homogeneous, isotropic and elastic, while the fluid was regarded as inviscid ...

Impact Structure and Morphology
2010The Mjolnir crater (Fig. 3.1) was first interpreted as an impact structure by Gudlaugsson (1993) based on its geophysical signature and overall geological setting. This inference was derived from a limited amount of multichannel seismic profiles, and regional gravity and magnetic profiles.

Graphene ultracapacitors: structural impacts
Physical Chemistry Chemical Physics, 2013The structural effects of graphene on the electrochemical properties of graphene-based ultracapacitors are investigated for the first time, where the competitive impacts resulting from the edge content, specific surface area, edge/basal defects, oxygen-containing groups and metal oxides/surfactant impurities are taken into consideration, demonstrating ...

Modeling of Impacts on Sandwich Structures
Mechanics of Advanced Materials and Structures, 2012In aeronautics, passenger safety and reliability of structures are essential aspects. Helicopter blades are particularly sensitive to impact solicitations but modeling these phenomena is still difficult and experimental tests often replace the prediction. This study will be focused on the modeling of an impact on the skin of the blade. It is equivalent

Acta Crystallographica Section D Biological Crystallography, 2007
Crystallographers are increasingly determining structures of protein constructs that include His tags. Many have taken for granted that these tags have little effect on the native structure. This paper surveys and compares crystal structures with and without His tags.

Inversion of regional gravity gradient data over the Vredefort Impact Structure, South Africa
, 2011We present the results for 3D inversion of gravity gradiometry data over the Vredefort Impact Structure in South Africa. With the rapidly growing field of gravity gradiometry, an investigation into the extraction of information from multiple components ...
