Degradation, damage evolution, and fatigue models in the literature for various engineering
materials, mostly metals and composites, are reviewed. For empirical models established …

Cross phenomena, representing responses of a system to external stimuli, are ubiquitous
from quantum to macro scales. The Onsager theorem is often used to describe them, stating …

Due to the restriction of lead-rich solder and the miniaturization of electronic packaging
devices, lead-free solders have replaced lead-rich solders in the past decades; however, it …

Low-cycle thermal-mechanical fatigue loadings induce progressive and permanent
degradation of mechanical properties of lead-free solder materials, and thus reduce the …

A series of ultrasonic vibration tests are performed on A656 grade steel samples, at a
frequency of 20 kHz. A fatigue life model based on the unified mechanics theory is …

This second edition adds new sections on derivation of dynamic equilibrium equations in
unified mechanics theory and solution of an example, derivation of very high cycle fatigue …

Fatigue life prediction of metals has been widely studied. However, most of the research is
based on empirical models under the framework of Newtonian mechanics, that relies on …

High-power white light-emitting diodes (LEDs) have demonstrated superior efficiency and
reliability compared to traditional white light sources. However, ensuring maximum …

Mechanics from its side and thermodynamics from its side consider evolution of complex
systems, including the Universe. Created classical thermodynamic theory of evolution has …

Formulated is a new instantaneous fatigue model and predictor based on ab initio
irreversible thermodynamics. The method combines the first and second laws of …
