A numerical study of the impact perforation of sandwich panels with graded hollow sphere cores
Advances in Mechanical Engineering, 2021 In this study, we numerically investigate the impact perforation of sandwich panels made of 0.8 mm 2024-T3 aluminum alloy skin sheets and graded polymeric hollow sphere cores with four different gradient profiles. A suitable numerical model was conducted

Blast response of continuous-density graded cellular material based on the 3D Voronoi model
Defence Technology, 2018 One-dimensional blast response of continuous-density graded cellular rods was investigated theoretically and numerically. Analytical model based on the rigid-plastic hardening (R-PH) model was used to predict the blast response of density-graded cellular

Likert Scaling Using the Graded Response Latent Trait Model [PDF]
Applied Psychological Measurement, 1983 The two-parameter graded response latent trait model was applied to data collected from a conven tionally constructed Likert-type attitude scale. Com parisons were made of both the person latent trait esti mates and the item parameter estimates with their counterparts from the conventional scaling method.
