Mechanical Characterization and Damage Modeling of Adobe Blocks Stabilized With Natural Plant Fibers

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study evaluates the mechanical performance of adobe blocks stabilized with natural plant fibers derived from Hyparrhenia hirta (HH) and Stipa offneri (SO). To this end, adobe specimens were fabricated by incorporating plant fibers into the soil matrix at contents ranging from 0% to 1% by weight of soil, with increments of 0.2%.

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

Applied 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

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

Advances 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 ...

Development and Validation of a Thermomechanically Coupled Plasticity Model at Elevated Temperatures

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Traditional material models often fail to accurately capture the cyclic behaviour of metals under combined thermomechanical loads, which leads to significant discrepancies in predicting material performance at elevated temperatures. This study develops and validates an advanced thermomechanically coupled plasticity model for G22NiMoCr5‐6 cast steel ...

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

International 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

Fatigue &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.

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

Journal 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.

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

Fatigue &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 ...
