From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

A model for the analysis of elasto-plastic buckling of compressed columns

, 2021
Modern structures often use new technology materials as special high-strength steels. This is one of the reasons why cross-sections of structural members are smaller and structures are lighter than those built fifty years ago. Besides, there are new calculation methods that try to optimize material use and save money. Engineers today are faced with new

A NEW APPROACH TO THE ELASTO-PLASTIC LATERAL BUCKLING STRENGTH OF BEAMS

Doboku Gakkai Ronbunshu, 1984
This paper is concerned with an interpretation and analysis on the elasto-plastic lateral torsional buckling of beams in a simplified manner by means of catastrophe theory. The numerical analysis does not require having recourse to the ordinary nonlinear numerical procedures, but can be performed using a relatively small microcomputer.The proposed ...

Study on the Shape Memory Performance of 4D‐Printed Auxetic Cellular Structures with Energy Absorption Application

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
4D‐printed auxetic cellular structures made from PETG demonstrate almost complete recovery of shape and mechanical properties after repeated loading. Two strategies successfully addressed the low shape‐fixity issue, the primary limitation of cold programming.

One‐Dimensional Finite Elements With Arbitrary Cross‐Sectional Displacement Fields

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT This paper introduces an unprecedented unified approach for developing structural theories with an arbitrary kinematic variable over the beam cross‐section. Each of the three displacement variables can be analyzed using an independent expansion function. Both the order of the expansion and the number of terms in each field can be any. That is,

Redundancy‐Based Seismic Safety Evaluation of Seismically Isolated Buildings

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
Seismically isolated buildings exhibit low redundancy, with damage progressing rapidly once the superstructure's response exceeds a critical threshold. This study formulates the relationship between the Ds value and ductility factor of the superstructure, enabling quantitative evaluation of quasi‐brittle behavior.

Numerical Model and Experimental Validation of Composite Metal Foam in Protecting Carbon Steel Against Puncture

Advanced Engineering Materials, Volume 28, Issue 1, January 2026.
The puncture prevention and energy absorption performance of composite metal foam (CMF) are studied experimentally and numerically for hazardous materials transportation protection. The numerical model implementing air within the CMF (nonhomogeneous model using fluid cavity technique) predicts puncture more accurately compared to the homogeneous CMF ...
