The critical thickness formula typically refers to the critical thickness of a thin film for a given material system. This critical thickness is the maximum thickness below which the film remains coherent and above which it becomes strained or even fragmented due to lattice mismatch or other factors. The critical thickness (tc​) can be calculated […]

Collision frequency, in physics, often refers to the rate at which particles collide within a system, such as in gases or plasmas. The collision frequency depends on various factors such as the density of particles, their velocities, and the cross-sectional area of interaction. The collision frequency, denoted by Z, can be calculated for a gas

The section modulus (S) is a measure of a beam’s resistance to bending stresses. It is defined as the ratio of the moment of inertia (I) to the maximum distance from the neutral axis (c) of the beam’s cross-section. Mathematically, it can be expressed as: ​ where: S = Section modulus (in meters cubed, m³)

The maximum bending stress (σmax​) is the highest stress experienced by a beam’s cross-section when subjected to bending moments. It usually occurs at the top or bottom fibers of the beam depending on the bending direction. The formula for maximum bending stress in a beam under a bending moment (M) can be given as: ​
