True Stress-Strain Curves Test and Material Property Analysis

The book "True Stress-Strain Curves Test and Material Property Analysis" offers a comprehensive analysis of the true stress-strain curves of two steels used in natural gas pipelines. By employing 3D digital image correlation (DIC) technology, the material behavior during the deformation process up to fracture is examined in detail. The results show that the true stress increases with strain after the necking point, revealing significant differences from the results of conventional methods. Additionally, a finite element model (FEM) is used to validate the true stress-strain curves. The book aims to deepen the understanding of material properties and explain various testing methods that are critical for the engineering assessment of pipelines. The data and methods provided are essential for the integrity and safety evaluation of pipeline systems.
