AlGaN strain strategies For AlGaN UV LEDs, which are typically grown on AlN templates, AlGaN strain-modulation strategies aim to mitigate the compressive stress. This can be realised by adjusting the ...

AI integration in materials testing accelerates evaluations, improves accuracy, and enables predictive quality assurance, ...

A stress-strain curve is a plot of the stress (force per unit area) versus the strain (change in length per unit length) of a material under a tensile or compressive load. A typical stress-strain ...

Mechanics of materials characterization of lead-free solder mechanical properties and stress strain curve properties are needed for applications in finite element analysis. In this study, tensile ...

where s 0.01 is the 0.01% proof stress. It is important to explain that the n value is obtained on the basis of the 0.01% and 0.2% proof stresses. The fitting can be seriously inaccurate above this ...

2.6 Ogden model Proposed in 1972 by Ogden 15, 16, this is also a phenomenological model and is based on principal stretches instead of invariants. The model is able to capture upturn (stiffening) of ...

The heteroepitaxy of high-quality aluminum nitride (AlN) with low stress is essential for the development of energy-efficient deep ultraviolet light-emitting diodes (DUV-LEDs). In this work, we ...
