Sentence examples for under normal impact from inspiring English sources
This property of the target is responsible for the deceleration of hard cored projectiles and for the erosion of long rods, under normal impact conditions.
A semi-analytical method to estimate the ballistic limit velocity (BLV) of bi-layer ceramic-metal armor under normal impact proposed in the International Journal of Impact Engineering, Vol 52 (2013) 37-46 is verified through gas gun experiments on alumina-aluminium armor system and simulations.
In contrast to their metal counterparts, it is interestingly found that absorbed energy generally increases with cell thickness, with a small extent of fluctuation, whereas core depth jumps, and the energy absorption capacity remains almost steady under normal impact but varies irregularly under the 45° impact.
Specific energy absorbed by each material considered are compared both under normal impact and oblique impact and the results confirmed that rubber absorbs 11.72 times more energy than structural steel, 3.24 times more energy than aluminium and 1.8 times more energy than glass epoxy, when subjected to normal impact.
The optimal solutions are obtained by numerical computation for ceramic/aluminum and ceramic/steel armor systems under the normal impact of NATO AP 7.62 rounds.
Integrated with related investigations, the present manuscript conducts systematical theoretical analysis on the interface defeat (the phenomenon where an impacting eroding projectile flows radially outward along the surface of target without any significant penetration) of long rods under the oblique impacts onto ceramic targets, and related comparison with the normal impact is also carried out.
Both the bulge and the hole were circular in normal impact and elliptical in oblique impact.
In addition, different failure patterns on the surface of CFRPs were observed under normal and oblique impact by in situ observation.
In addition, 35S::AtAPY1-GFP seedlings were cultured under normal conditions to minimize any impact the alkaline culture medium may have on AtAPY1 distribution and infiltrated with buffer of pH 7.5 just for imaging.
The control experiment and several idealized test cases on influential factors in scour depth reveal that the dominant hydrodynamic factor is tidal current in the ECS under normal weather conditions, and the impacts of shelf circulation and wave motion on local scour almost can be ignored with an exception of the Kuroshio area where the high-speed mainstream of Kuroshio flows.
Under normal operating conditions, the potential impacts at each of the proposed locations such as noise, traffic, and waste management were judged to be "negligible," "minor," or "moderate".
