If Q is the point load and σ z is the vertical stress due to the point load, σz = Q 2πz2 × √(1 − 2μ) / (2 − 2μ) [(1 − 2μ) / (2 − μ) + (r / z)2)]3 / 2 = Q z2Iw. Here, μ= Poisson's Ratio. If Poisson's Ratio is considered zero for all practical purposes, σz = Q πz2 × 1 [1 + 2(r / z)2)]3 ...

WebThe original equations developed by Westergaard (1926 [2]) for three critical load locations will be presented. The critical load locations are (after Bradbury, 1938 [1] and Westergaard, 1926 [2]): Interior loading. Occurs when a load is applied on the interior of a slab surface which is “remote” from all edges. Edge loading. Occurs when a ...

WebCenter for Transportation Research UT Austin WebFollowing the same approach as Skarlatos and Westergaard, closed-form equations are derived for the maximum deflection and maximum bending stress occurring on the unloaded side of an edge capable of load transfer. Together with Westergaard's 1948 free edge equations, the two unloaded side formulas effectively extend Westergaard's solutions to ...

WebFrom figure 8.3 it is clear that the Westergaard equation gives values consistently less than the Boussinesq for the same point load up to a ratio r/z equal to 1.5. When the ratio exceeds 1.5, the Westergaard formula gives greater stress. For all ratios or r/z less than about 0.8, the vertical stress as per Westergaard’s formula is ...

WebIn 1939, Harold M. Westergaard developed a solution for the stress field surrounding a crack that has two advantages over Inglis's solution [2]. First, Westergaard's solution applies directly to cracks, not to an ellipse that approaches a crack in the limit. Second, the solution is expressed in rectangular coordinates rather than elliptical coordinates.
