A multiphase model for reinforced concrete structures considering the concrete cracking

open access: yesRevista IBRACON de Estruturas e Materiais
Assessing the global behavior of reinforced materials from the individual properties of their components has been the subject of a considerable amount of experimental and theoretical works in the last years.

A mathematical model of network elastoplasticity

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022
We introduce a mathematical model, based on networks, for the elasticity and plasticity of materials. We define the tension tensor for a periodic graph in a Euclidean space, and we show that the tension tensor expresses elasticity under deformation. Plasticity is induced by local moves on a graph. The graph is described in terms of the weights of edges,

Origami Metamaterials Based on Low‐Melting‐Point Alloy Phase Transition: Breaking the Trade‐Off Between Reusability and Energy Absorption Quality

open access: yesAdvanced Science, EarlyView.
This work presents an origami metamaterial that integrates a low‐melting‐point alloy skeleton into an elastomeric shell. It dissipates energy through the metal's plastic deformation and recovers through the solid–liquid phase transition of the alloy together with the hyperelasticity of the shell.

Equilibrium and stability of beams with elastoplastic semi-rigid joints [PDF]

open access: yesArchives of Civil Engineering
The classical theory of beams admits two types of connections between structural elements: perfectly rigid and perfectly flexible. However, the engineering reality calls for a more general approach to joint modelling.

AI‐BioMech: Deep Learning Prediction of Mechanical Behavior in Aperiodic Biological Cellular Materials

open access: yesAdvanced Intelligent Discovery, EarlyView.
AI‐BioMech is a deep learning framework that predicts the mechanical behavior of biological cellular materials directly from 2D images. By replacing traditional finite element analysis with semantic segmentation, it identifies stress and strain distributions with 99% accuracy, offering a high‐speed, scalable alternative for analyzing complex, aperiodic

Springback prediction of sheet metal in the deep drawing process using elastoplastic phenomenological models [PDF]

open access: yes, 2005
The deep drawing is one of the widely used processes in industry to give suited forms to metal sheets. During deformation the sheet and tools undergo high stresses. The sheet must carry on the deformation until the end of the process.

A model for the evolution of laminates in finite-strain elastoplasticity [PDF]

open access: yes, 2011
We study the time evolution in elastoplasticity within the rate-independent framework of generalized standard materials. Our particular interest is the formation and the evolution of microstructure. Providing models where existence proofs are possible is

Eulerian elastoplasticity: Basic issues and recent results [PDF]

open access: yesTheoretical and Applied Mechanics, 2009
Traditional formulations of elastoplasticity in the presence of finite strain and large rotation are Eulerian type and widely used; they are based upon, among other things, the additive decomposition of the stretching or the Eulerian strain-rate into ...

Elastoplastic Deformations of Layered Structures

open access: yesMilan Journal of Mathematics, 2022
We formulate a large-strain model of single-slip crystal elastoplasticity in the framework of energetic solutions. Numerical performance of the model is compared with lab experiments on the compression of a stack of note papers.
