We can also consider the beam's surface as our reference point as long as there are no changes in the beam's height or depth during the bending. We have tabulated these formulas for you, as shown below: Simply-supported beam deflection formulas. The equations are also only reasonably accurate if the thickness is less than 10% of the Simply supported rectangular plate with point load. Calculating beam deflection requires knowing the stiffness of the beam and the amount of force or load that would influence the bending of the beam. Consider a simply supported beam of length L = 10m with a uniform load (force per unit length) of w = 5 kN/m acting on it. Engineering Calculators Choose the best formula Cantilever beam: The formula for the deflection of a cantilever beam is (WL**3**)/(3EI) Simply supported . A method is for efficiently determining a very large number of terms in the series. Understanding and constructing shear force diagrams is an essential part of the structural analysis process.

Alternatively, use our 'Import from Design Code' function to automatically assign the loads you created to the specific load combinations prescribed by your region's Design Code! interface. Rectangular Plate Calculator (deflection & stress) Unlike a disc ( circular plate ), where stresses and deflections are generally predictable owing to constant edge support, in a sheet (rectangular plate) - where edge supports vary - they are much less predictable. The input for material can be changed to suite whatever material you wish to design. The modulus of elasticity depends on the beam's material. . Beam Deflection and Stress Formula and Calculators 0.176 MPa. Deflection for simply supported beam can be calculated by the equation below: = 5wL 4 /384EI. Straight lines in the plate that were originally vertical remain straight but become inclined; therefore the intensity of either principal stress at points on any such line is proportional to the distance from the middle surface, and the maximum stresses occur at the outer surfaces of the plate. The supports are located at points A and B.
