WebA stress-strain average curve was plotted using the average measured values. This curve was subsequently used to define the stress-strain model curve in the SolidWorks® application (Vláčilová et al. 2007). This way, the basic stress-strain curve was created for the hard and soft wood species specimens. WebIn materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be …
