WebThen, PZR effects are modeled based on stress concentration and piezopinch effects. Stress concentration as a function of the physical geometry of SiNWs can amplify PZR effects by an order of magnitude. The piezopinch effects can also result in increased PZR effects that are at least two times greater than that of bulk silicon. WebFeb 20, 2024 · 12.5: Stress, Strain, and Elastic Modulus (Part 2) Bulk stress causes a change in the volume of an object or medium and is caused by forces acting on the body from all directions, perpendicular to its surface. Compressibility of an object or medium is the reciprocal of its bulk modulus, the elastic modulus in this case.
