Energy absorption characteristics of additively manufactured plate-lattices under low- velocity impact loading

Journal: :International Journal of Impact Engineering 2021

Abstract This study is focused on the low-velocity impact response of 3D plate-lattices fabricated via stereolithography additive manufacturing (AM). Elementary (SC, BCC and FCC) hybrid (SC-BCC, SC-FCC SC-BCC-FCC) configurations were tested effects energy, relative density, plate-thickness, multiple impacts angle dynamic crushing behavior energy absorption characteristics analyzed. The experime...

Low-Velocity Halo Clouds

2008

J. E. G. Peek Carl Heiles M. E. Putman Kevin Douglas

Models that reproduce the observed high-velocity clouds (HVCs) also predict clouds at lower radial velocities that may easily be confused with Galactic disk (|z| < 1 kpc) gas. We describe the first search for these low-velocity halo clouds (LVHCs) using IRAS data and the initial data from the Galactic Arecibo L-band Feed Array survey in Hi (GALFA-Hi). The technique is based upon the expectation...

بررسی عددی و شبیه سازی رایانه ای مدل فنر- قطعه

ژورنال: پژوهش فیزیک ایران 2001

محمدرضا سرکرده ای, ,

We present numerical solutions of the equations of motion of the driven spring-block model with stick-slip dynamics. The system consists of an array of N masses which describes the statistical and dynamic properties of dissipative systems. In this study, we are interested in very low and very high velocity regimes. We show that there is a clear shift in the distribution of slip-force when we ...
