How are the deflections of a beam determined?
The Elastic Curve Deflections at specific points on a beam must be determined in order to analyze a statically indeterminate system. 3 Beam Deflection by Integration The Elastic Curve The curve that is formed by the plotting the position of the centroid of the beam along the longitudal axis is known as the elastic curve.
What is the deflection of a cantilever beam?
Steel graph for cantilever show very abnormal values of displacement. ¼ span of steel shows only 0.4 mm deflection at the highest load and ½ spans shows 2.5 mm deflection at highest load
Which is the flexural rigidity of the beam?
The product EI is called the flexural rigidity of the beam. The first integration y' yields the slope of the elastic curve and the second integration y” gives the deflection of the beam at any distance x. The resulting solution must contain two constants of integration since EI y" = M is of second order.
When to use Hooke's law for deflection of beams?
EIv" = M EIv"' = V EIv"" = - q this equations are valid only when Hooke's law applies and when the slope and the deflection are very small for nonprismatic beam [I = I(x)], the equations are d2v EIxCC = M dx2
