Large Deformation Pile‐soil Interaction Under Lateral Vehicle Impact Using Hybrid SPH+FEM and EFG+FEM Models

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2648-2669, 10 April 2026.
ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

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.

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.

The influence of the accuracy of reproducing the uniaxial tensile test of mild steel in the H–M plasticity model on the behaviour of a perforated thin walled shell subjected to compression [PDF]

Archives of Civil Engineering
The article describes the impact of modeling the plasticity constitutive relationship on the buckling of a short section of a perforated thin-walled steel bar with an open cross-section (modeled as a perforated shell) subjected to compression, being one ...

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 ...

Research on the Mechanical Characteristics and Deformation of Windings and Spacers of Power Transformer Under Short‐ Circuit Condition

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Based on experimental tests with radial spacers, this paper proposes a winding vibration analytical method using the Mooney‐Rivlin 5‐order model to describe the winding vibration characteristics with spacers. Taking a 40,000 kVA/110 kV transformer as an example, the electromagnetic and axial vibration characteristics of the windings under sudden short ...
