A Matrix‐Free, Scalable, and Robust Implicit Material Point Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT An implicit material point method is presented using a new dynamic relaxation solver, allowing for a simple and efficient quasi‐static formulation that may be readily implemented in existing explicit‐dynamic codes. The use of dynamic relaxation and aggregation is shown to produce an extremely robust material point method scheme, with good ...

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

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Triply‐Twinned Metamaterials: Unraveling the Mechanics and Failure Pathways Through High‐Resolution XCT

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...

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 ...

Local Elasto–plastic Buckling of Isotropic Plates With Cutouts Under Tension Loading Conditions

International Journal of Mechanics, 2021
The motivation of the presented study was the observation of the existence of local loss of stability “tension buckling” in the experimental tests of composite and metallic plates with cut-outs subjected to tension. Because of this, the numerical analyses of the aluminum plate with elliptical or circular cutouts at the center and subjected to tensile ...
