AbstractTraditionally, stress strain curves for example from tensile testing are described with empirical models with a number of adjustable parameters such as Hollomon, Ludwik, Voce and Swift. With such models it is difficult or impossible to generalize and extrapolate.

Characterizing the true stress-strain curve of CrAlN coatings by nanoindentation using finite element-reverse analysis [PDF]
MATEC Web of ConferencesThis paper proposes a methodology to convert thin film nanoindentation load-displacement curves into tensile stress-strain curves. An optimization procedure, based on the trust-region reflective algorithm, is established to identify a unique set of three

Dynamic Recrystallization Behavior and Critical Conditions of SiCp/A1-Cu Composite
Journal of Aeronautical Materials, 2017 Using the Gleeble-1500D simulator, the high temperature plastic deformation behavior of 40%SiCP/Al-Cu composite were investigated at 350-500℃ with the strain rate of 0.01-10 s-1. The stress-strain curves were obtained during the tests.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...
