jännitysvenymäkokeessa
Jännitysvenymäkoe, known in English as a tensile test, is a fundamental mechanical test used to determine a material's resistance to deformation under tension. During the test, a standardized specimen of the material is subjected to a gradually increasing tensile load until it fractures. The data collected from this process provides crucial information about the material's mechanical properties.
The test involves carefully measuring the force applied to the specimen and its corresponding elongation. This
The initial linear portion of the stress-strain curve represents the elastic region, where the material deforms
Further analysis of the stress-strain curve allows for the determination of the yield strength, the stress
