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 ...

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

Fatigue &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.

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.

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

Advanced 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

Fatigue Design Curves for Industrial Applications: A Review

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 3, Page 1001-1021, March 2025.
ABSTRACT In the present paper, a review on the design curves for safe–life fatigue design is provided. The methodologies available in the literature for the assessment of the strain–life and stress–life design curves have been analyzed, focusing also on the industrial practice for the design of critical components.

Structural Performance Evaluation of Composite Beams With Different Shear Transfer Mechanisms at Beam‐Slab Interface

JAPAN ARCHITECTURAL REVIEW, Volume 8, Issue 1, January–December 2025.
ABSTRACT In general, a steel beam is connected to a concrete slab using shear connectors, forming a composite beam. This composite action shifts the neutral axis under bending, resulting in a buckling behavior that differs from that of a bare steel beam.

Low Cyclic Fatigue Properties and Cyclic Constitutive Modeling of SS275 Steel for Seismic Applications

Buildings
Steel energy dissipation devices are integral to seismic design, as they help reduce structural deformations during strong earthquakes by absorbing and dissipating energy through large inelastic deformations.

Parameter-refreshed Chaboche model for mild steel cyclic plasticity behaviour

Periodica Polytechnica Civil Engineering, 2013
The development of a steel material model in order to follow the cyclic plastic behaviour is essential in seismic design. The authors present an improved Chaboche model for the cyclic mechanical behaviour of structural steel. The model is based on the combination of nonlinear kinematic and multi-linear isotropic hardening with a parameter refreshing ...
