Stress and strain exceeding the proportional limit
of the material are presented in bold.
Investigators were most interested in the acoustic velocity response within wood that had been loaded into the range over and above the proportional limit
Similar to the bark specimens, meaningful values for maximum crushing strength could not be determined for the wood specimens tested in the radial direction because of continuous densification as the stress increased beyond the proportional limit
Close to the proportional limit
, the sample starts to move laterally and to embed in the lower anisotropic strength direction.
From the [sigma]-[epsilon] relation, Young's modulus, proportional limit
stress, and compressive strength were determined by the following procedure.
They cannot determine the shear stress/shear strain behavior including the shear modulus and shear stress at the proportional limit
This limitation may similarly apply to the proportional limit
stress and bending strength obtained under the standardized span/depth ratio range.
The objective of the current study is to expand the knowledge base for this subject by exploring the influence of end distance on the tensile behavior (specifically stiffness, proportional limit
, yield load, and ultimate load) of mortise-and-tenon wood pegged joints using three commonly used species: eastern white pine, Douglas-fir, and red oak.
2) Based on the combination of percentage changes in elastic modulus and stress at the proportional limit
, the specimens from locations Left C 30 and Right C 30 were concluded to contain incipient decay.
From the obtained data, the MOE, modulus of rupture (MOR), and stress at proportional limit
of each specimen were determined.
The effect of outdoor exposure is greatest on values of fiber stress at proportional limit
(FSPL) on all species tested.
As the Head of Government underlined, the document will determine proportional limits
of actions of law enforcement structures during searches, will establish the responsibility of officials of law enforcement authorities for illegal activities during the conduct of investigative actions and other procedural measures, will impose the obligation of video recording investigations, define clear terms pretrial investigation and other procedural deadlines in criminal proceedings, etc.
