In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing).
Stress-strain curves are an extremely important graphical measure of a material’s mechanical properties, and all students of Mechanics of Materials will encounter them often. However, they are not without some subtlety, especially in the case of ductile materials that can undergo sub- stantial geometrical change during testing.
Learn how to graph and interpret stress-strain curves, which show the relationship between stress and strain in materials. Explore the basic principles, historical development, applications, and advanced topics of stress-strain analysis in Solid Mechanics.
23 sie 2001 · Learn how to interpret stress-strain curves, which measure a material's mechanical properties under tension. Find out the difference between engineering and true stress, yield and fracture stress, and strain hardening and softening.
26 maj 2024 · Stress, defined as the force per unit area (σ = F/A), measures the internal forces within a material. Strain, on the other hand, is the measure of deformation representing the displacement between molecules in the material (ε = ΔL/L 0). There are several key points on the stress-strain curve:
