Stability of columns with no tension strength and bounded compressive strength and deformability. Part I: large eccentricity

This work concerns the stability of piles with rectangular cross section, made of a no-tension material with limited compressive strength and deformability, subjected to an axial load acting within the cross section but outside its middle third (large eccentricity). The differential equations obtained have been solved explicitly, and their solutions have allowed us to describe the stability characteristics of the pile through graphical representations
