👉 Non-isoelastic refers to a material that has a high degree of plasticity but is not elastic. It means that it exhibits an increase in stress as the strain increases, and this behavior can lead to failure or deformation under certain conditions. For example, a steel rod with a very high ratio of elongation (e.g., 100%) will exhibit nonisoelastic behavior because the material has a high degree of plasticity. This means that it will not deform in response to external
