Effectiveness of double cutout on lateral buckling analysis of fiber reinforced composites

Polymer Composites, Volume 45, Issue 12, Page 10880-10887, 20 August 2024.
Lateral buckling test mechanism. Abstract Lateral buckling, an essential mechanical phenomenon observed in composite beams subjected to specific external loads and boundary conditions, is influenced by various factors including cutout dimension, shape, position, and beam thickness in woven fabric laminated composite cantilever beams.

Soft Kirigami Composites for Form‐Finding of Fully Flexible Deployables

Advanced Materials Technologies, Volume 9, Issue 1, January 8, 2024.
A new class of thin flexible structures are introduced that morph from flat into prescribed 3D shapes without an external stimulus such as mechanical loads or heat. To achieve control over the target shape, two different concepts are coupled: strain mismatch (inspired by biological growth) and kirigami cuts.

Energy‐Balance‐Based Plastic Design and Seismic Fragility Analysis of Steel Plate Shear Wall Coupled with Steel Side Columns

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
The steel plate shear wall (SPSW) coupled with steel side columns (SSCs) through steel coupling beams, or the SPSW–SSC coupled structural system, is a novel lateral force resisting system that introduces coupling mechanism to the isolated SPSW pier. To simplify the complex iteration of the conventional seismic design procedure and obtain the favorable ...
