A Transition State Theory-Based Continuum Plasticity Model Accounting for the Local Stress Fluctuation

Metals
Based on the transition state theory, a continuum plasticity theory is developed for metallic materials. Moreover, the nature of local stress fluctuation within a material point is considered by incorporating the probability distribution of the stresses.

Evaluation of Rotation Capacity and Bauschinger Effect Coefficient of I-Shaped Beams Considering Loading Protocol Influences

Buildings
Recent catastrophic earthquake events have reinforced the necessity of evaluating the seismic performance of buildings. Notably, the buildings can go into the plastic phase during a striking earthquake disaster.

The Bauschinger effect

, 1953
If a work-hardenable metal is deformed plastically by a tensile stress +σ₀ and unloaded, its mechanical properties become anisotropic; in particular, though its tensile yield stress is now +σ₀, it will deform plastically if compression stresses numerically smaller than σ₀ are applied. This is known as the Bauschinger effect (Bauschinger 1886).

A finite strain thermo-mechanically coupled material model for semi-crystalline polymers [PDF]

, 2019
In this work, a thermo-mechanically coupled constitutive model for semicrystalline polymers is derived in a thermodynamically consistent manner. In general, the macroscopic material behaviour of this class of materials is dictated by the underlying ...
