SUMMARY
Incompressible materials are defined as substances that do not change in volume when subjected to stress, exemplified by materials like rubber. The scientific definition states that the derivative of specific volume (volume per unit mass) with respect to the sum of the three principal stresses equals zero. This concept is crucial in fields such as ultrasound elastography, where understanding material properties is essential for accurate analysis. The discussion highlights the need for clarity in defining incompressibility, particularly in academic contexts.
