Spenningtøyningskurver
Spenningtøyningskurver, also known as stress-strain curves, are graphical representations that illustrate the relationship between stress and strain in a material when subjected to an applied force. Stress is defined as the internal resistance per unit area that a material offers to an external force, typically measured in units of Pascals (Pa) or pounds per square inch (psi). Strain, on the other hand, is the measure of deformation experienced by the material in response to the applied stress, usually expressed as a dimensionless ratio or a percentage.
These curves are fundamental in materials science and engineering for characterizing the mechanical behavior of materials.
A typical spenningtøyningskurve for a ductile material begins with a linear elastic region where stress is
Different materials exhibit distinct spenningtøyningskurver. Brittle materials, for instance, show little or no plastic deformation before
