Low velocity impact and quasi-static in-plane loading on a graded honeycomb structure; experimental, analytical and numerical study

摘要: Abstract Through the increasing development of technology in different industries, and integral requirement energy absorption, light shock absorbers such as honeycomb structure under in-plane out-of-plane loads have been center attention. The purpose this research is to analyze behavior graded (GHS) low-velocity impact quasi-static loading. To begin with using lower-bound theorem, an analytical equation for plateau stress represented, taking power hardening model into consideration. compare acquired equations, empirical tests are conducted on test specimens made aluminum 6061-O, previously mentioned Uniaxial tensile each row material performed collect data properties. Drop-weight Santam compression machines, respectively. study strain rate effect structure. Two experimental simulated ABAQUS/CAE. Based comparisons, numerical results indicate a satisfactory agreement results. Given comparison between mode shapes, “V” deformation distinguished specimen.
