Seismic Design Gaps and Link Innovations: Evaluating Gusset Connected Box and I‐Shaped Links in Multi‐Tiered EBFs

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study addresses a critical gap in seismic design codes by evaluating the nonlinear performance of multi‐tiered eccentrically braced frames (MT‐EBFs) and offering practical recommendations for future provisions. MT‐EBFs, an advanced variation of conventional EBFs, incorporate multiple tiers of links and braces within a single story, making them ...

Cyclic Elasto-Plastic Behaviour of 51CrV4 Steel for Railway Parabolic Leaf Spring Design

open access: yesApplied Sciences
Parabolic leaf springs are components typically found in suspensions of freight railway rolling stock. These components are produced in high-strength alloyed steel, DIN 51CrV4, to resist severe loading and environmental conditions. Despite the material’s

Physics‐Informed Deep Learning Constitutive Model for Anisotropic and Pressure‐Dependent Behavior of Short Fiber‐Reinforced Polymers

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 19, 15 October 2025.
ABSTRACT Short fiber‐reinforced polymers (SFRPs) exhibit complex anisotropic, nonlinear, and pressure‐dependent behavior due to their heterogeneous microstructures. Conventional constitutive models, while accurate, require extensive parameter calibration and may lack generalization capability under varied loading conditions.

Modeling of Crack Propagation in Ductile Materials Under Cyclic, Proportional and Non‐Proportional Loading Conditions

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 10, Page 4505-4516, October 2025.
ABSTRACT The paper addresses the numerical calculation of multi‐axial fatigue crack propagation in ductile materials under proportional and non‐proportional cyclic loading conditions. The analysis is based on a phase field fracture theory proposed in earlier work, which describes crack propagation on the basis of the evolution of plastic strain.

Ratcheting behavior of cylindrical pipes based on the Chaboche kinematic hardening rule

open access: yes, 2012
In this study, cyclic loading behavior of thick cylindrical pipes are described. Effects of internal pressure level and axial strain amplitude on the ratcheting rate under different types of loading histories are investigated.

Fatigue Prediction of 50% Short Fiber‐Reinforced Polyphthalamide Using Equivalent Stress Criteria and Critical Distance Methods

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 7, Page 2949-2964, July 2025.
Abstract Accurately predicting the fatigue lifetime of short fiber‐reinforced polymers (SFRPs) remains a significant challenge in the automotive industry, especially in the presence of sharp geometric discontinuities. This study presents a practical approach for estimating the fatigue life of injection‐molded notched SFRP specimens, considering ...

Influence of Induction Hardening on Wear Resistance in Case of Rolling Contact

open access: yesJournal of Mechanical Engineering, 2016
The main aim of the presented paper is to show how heat treatment, in our case the induction hardening, will affect the wear rates as well as the ratcheting evolution process beneath the contact surface in the field of line rolling contact.

A Plastic Damage Model With Mixed Isotropic–Kinematic Hardening for Low‐Cycle Fatigue in 7020 Aluminum

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 6, Page 2649-2668, June 2025.
ABSTRACT The paper at hand presents a new numerical model based on experimental investigations of the low‐cycle fatigue behavior of the high‐strength aluminum alloy EN AW‐7020 T6. The developed plastic damage model is based on J2 plasticity with Charboche‐type mixed kinematic hardening blended with a suitable isotropic hardening.

A Workflow‐Centric Approach to Generating FAIR Data Objects for Computationally Generated Microstructure‐Sensitive Mechanical Data

open access: yesAdvanced Engineering Materials, Volume 27, Issue 8, April 2025.
A novel metadata schema is introduced to address the sparsity of microstructure‐sensitive mechanical data. The design follows the material modeling workflow, as each run results in the definition of unique data objects. The schema includes categorical elements to ensure findability, accessibility, interoperability, and reusability (FAIR). This approach

Investigation of advanced strain-path dependent material models for sheet metal forming simulations [PDF]

open access: yes, 2006
Sheet metal forming processes often involve complex loading sequences. To improve the prediction of some undesirable phenomena, such as springback, physical behavior models should be considered.
