A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Energy Dissipation in Nonlinearly Elastic Auxetic and Non‐Auxetic Mechanical Metamaterials with Friction and Material Damping

Advanced Engineering Materials, EarlyView.
This study presents a hyperelastic mechanical metamaterial for elastic energy dissipation. Energy is dissipated within its unit cells by friction assisted by material damping. Frictional contact is enhanced when using auxetic unit cells. The load–displacement plot for one compression cycle shows a pronounced hysteresis loop, indicating that a large ...

Novel Surface‐Based Bézier Metamaterials: A Higher Degree of Parametrization toward Tailoring the Effective Properties under Compression

Advanced Engineering Materials, EarlyView.
Cubic Bézier curves are used in the synthesis of novel surface‐based metamaterials with tunable mechanical properties. Surface‐based geometries are 3D printed and tested in compression. The resulting mechanical properties are correlated to changes in the shape of the base curve, with high potential in energy absorption through the adjustment of their ...

A Simulative Evaluation of Triply Periodic Minimal Surface Structures in the Context of Elastocaloric Applications

Advanced Engineering Materials, EarlyView.
A simulative evaluation of triply periodic minimal surface (TPMS) structures for an elastocaloric application under compressive load is performed. For the evaluation of the structure's performance, surface/volume ratio, generated heat and invested mechanical work are taken into account and are compared to a tube as a reference specimen.

Evaluation Strategies of Hil48 Yield Criterion in Application: Toward Sufficient and Necessary Conditions for Prediction of Plastic Anisotropy

Advanced Engineering Materials, EarlyView.
This article presents a comprehensive analysis of the intrinsic relationships and applicability of Hill48 yield criterion. The applicability and error evaluation conditions for Hill48 are established based on specific experimental data. A parameter calibration strategy for N‐value based on error minimization is proposed, and the predictive accuracy is ...
