Assuming the beam undergoes small deflections, is in the linearly elastic region, and has a uniform cross-section, the following equations can be used (Gere, p. 602). The curvature of the beam,, is equal to the second derivative of the deflection

Analysis of Beams and Plates for Ponding Loads. The ponding problem as characterized by the fact that the magnitude of loads is dependent on deflection is formulated. The governing differential equations for beams and plates are derived and solved for various boundary conditions. As a stability problem, the critical ponding ratios are determined.

    Deflection of Beam: Deflection is defined as the vertical displacement of a point on a loaded beam. There are many methods to find out the slope and deflection at a section in a loaded beam. The maximum deflection occurs where the slope is zero. The position of the maximum deflection is found out by equating the slope equation zero.

    These equation systems are linear if the corresponding PDE is linear and vice versa. Algebraic equation systems are solved using numerical linear algebra methods. The ordinary differential equations that arise in transient problems are numerically integrated using techniques such as Euler's method or the Runge-Kutta method.

    difference between the deflection as found by the classical beam theory and that found by the present method is, however, noticeable only in the case of beams of low stiffness. The clamped end of the beam is taken as the origin of coordinates and downward deflections are considered as positive.

    dimensional Laplace equation The second type of second order linear partial differential equations in 2 independent variables is the one-dimensional wave equation. Together with the heat conduction equation, they are sometimes referred to as the “evolution equations” because their solutions “evolve”, or change, with passing time.
