A homogenization method for geometric nonlinear analysis of sandwich structures with initial imperfections

International Journal of Solids and Structures, 2016
Abstract A homogenization method for geometric nonlinear analysis of structural core sandwich panels is proposed. The method provides high computational performance based on an efficient separation of scales. In the macroscale, the sandwich panel is discretized with an equivalent single layer of shell elements.

Experimental and Analytical Studies of Door-Type Modular Scaffolds with Initial Geometrical Imperfections

Engineering Journal, 2018
In the study, the performance and structural behaviors of door-type modular steel scaffolds with different degrees of initial geometrical imperfections were evaluated through experimental and analytical investigations. Two one-story and nine two-story modular steel scaffolds were tested to failure. When the number of stories increased from 1 to 2, a 14.
