Dislocation-associated elastic energy storage in mechanical
In the case of the single segment dislocation model, Fig. 1, it is easy to show that the elastically stored energy in the forward deformation cycle with ε 1 applied strain is (Δσ × ε 1 )/2 and thus the energy parameter becomes: β E = [ ( Δ σ × ɛ 1) / 2] / ( σ 0 + Δ σ / 2) ɛ 1 giving a positive value considerably smaller than 1.0.
Wood‐Derived Lightweight and Elastic Carbon Aerogel for Pressure
