Development and Validation of a Thermomechanically Coupled Plasticity Model at Elevated Temperatures

Advances in Materials Science and Engineering
Traditional material models often fail to accurately capture the cyclic behaviour of metals under combined thermomechanical loads, which leads to significant discrepancies in predicting material performance at elevated temperatures.

Theory of Plasticity

, 2006
Plasticity is concerned with the mechanics of materials deformed beyond their elastic limit. A strong knowledge of plasticity is essential for engineers dealing with a wide range of engineering problems, such as those encountered in the forming of metals,
