Does the magnitude or range of interaction of a force affect which layer dominates the mechanical response of a multilayered structure?
Suppose I have a two-layered material, with a stiff and thin outer layer (high E) and a soft (low E) and thick inner layer.
Intuitively, it feels like the effect of short-ranged forces (e.g., van der ...

Calculating the bending moment ($M$) of a beam as it relates to stress ($σ$) and strain ($ε$)?
I am trying to learn how to work out the bending moment for progressively complex systems to model a beam. I am assuming only one axis of motion (transverse = $y$).
For the basic equation of material ...

Quantifying the amount of structural/hysteretic vibrational damping that occurs in proportion to deformation? (ie. Based on how "bent" something is?)
Three different conceptual types of vibrational damping forces are described here:
Viscous: $f(t) = -c \cdot v$
Coulomb: $f(t) = -c \cdot \text{sgn}(v)$
Structural: $f(t) = -c \cdot |x| \cdot \text{...
