Description	DEFPIG calculates the deformations and load distribution within a group of piles subjected to vertical, horizontal and moment loading. The program considers a group of vertical elastic piles having axial and lateral stiffness that are constant with depth. The piles are supported by a linear elastic medium, but the program allows for the possibility of slippage between the piles and the soil under axial loading and for the development of yield of the soil adjacent to the pile due to lateral loading. The stress distributions are computed from Mindlin's solutions for an isotropic homogeneous linear elastic medium, but nonhomogeneity of the soil along the pile length can be approximately taken into account. The piles are assumed to be attached to a rigid pile cap, so that all undergo equal lateral deflection and rotation or alternatively, can be subjected to specified loads or deflections. Raking or battered piles may be present in the group, but only battered in the direction of the lateral loading. Load-deformation relationships to failure may be obtained if desired. Any constant set of units may be used. A demonstration version is available on the WWW.
