Basics of Material Creep
In Basics of Material Creep, you'll learn ...
- The basics of the material creep phenomenon and the equations governing it
- The typical three stages of material creep, and the differences between them
- The influence of temperature and stress variations on the creep phenomenon
- The material properties that affect material creep
In late 19th Century, it was observed that some materials deform permanently after being exposed for a long time to less than critical conditions: stresses below yield point and high temperatures that are significantly below the melting point. This phenomenon has been called “Material Creep.” While not always leading to actual component rupture, the significant geometrical changes induced by creep can significantly affect the performance of the associated machinery. As modern industrial applications are demanding ever-increasing stresses and temperatures, creep mitigation is gaining more importance in engineering analysis and design.
This course presents the fundamental concepts that govern the creep phenomenon in crystalline metallic materials. Going beyond the theory, the course introduces a few design considerations that can aid the engineer in managing the creep conditions: the typical creep design iterations, the Larson-Miller Parameter method, and guidelines to selecting materials that resist creep regimes. A few practical cases are shown to illustrate the associated methods and formulae, which include discussions in the larger engineering contexts.
This course will help Design Engineers, Quality and Forensic Engineers, Engineering Project Managers, and Engineering Managers who are interested in understanding creep phenomenon.
