Southwell Plot
The Southwell plot is a graphical method of determining experimentally a structure's Structural load, critical load, without needing to subject the structure to near-critical loads.Mandal, P., & Calladine, C. (2002). Lateral-torsional buckling of beams and the Southwell plot. International Journal of Mechanical Sciences, 44(12), 2557-2571. doi:10.1016/s0020-7403(02)00192-3 The technique can be used for nondestructive testing of any structural elements that may fail by buckling.Stability Of Structures: Additional Topics.

The differential equation of equilibrium is \frac + \alpha^2\frac(v-v^o)=0, \alpha^2=\frac where ''v''''o'' is the initial deflection, and the boundary conditions are v(0)=v^(0)=v(L)=v^(L)=0 Assuming that the deflected shape can be expressed as a Fo ...

Experimental Southwell Plot
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into Causality, cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experiment, natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and i ...
