A new technique is described to quantify particle shape and angularity using an image analyser. The method relies on discretising the two-dimensional projection of the particle and comparing the projected outline with that of a standard geometric shape, namely a circle. Two new parameters for particle shape and angularity were formulated and their values were determined for various materials. The relationship between the new parameters and large-strain (steady-state) internal friction angle as well as pluviated void ratio was examined. Overall, the results indicate that as shape and angularity parameters increase, the drained friction angle and pluviated void ratio increase. In addition, shape and angularity were found to influence the measured maximum void ratio and, to a lesser extent, the minimum void ratio.

This paper documents the use of finite element analyses techniques to determine the capacity of suction caisson foundations founded in soft clays under undrained conditions. The stress-strain response of the soft clay is simulated using an elasto-plastic model. The constitutive model employed is the classical von Mises strength criterion with linear elasticity assumed within the yield/strength surface. Both two-and three-dimensional foundation configurations are analyzed. The three-dimensionality of the failure surface of the actual caisson requires that computationally intensive threedimensional models be used. Suggestions are given on how to improve computational efficiency by using quasi three-dimensional Fourier analyses with excellent results instead of true three-dimensional analyses. The finite element techniques employed are verified against available classical limit solutions. Results indicate that both hybrid and displacement-based finite element formulations are adequate, with the restriction that reduced-integration techniques are often required for displacement-based formulations.

This panel brings together a group of men with diverse backgrounds and experiences to discuss their perspectives and offer practical skills for men to effectively serve as advocates for gender equity. This paper augments the panel and captures the backgrounds, experiences, perspectives, and recommendations of the panelists, thereby providing a lasting resource for those unable to attend the panel or future interested individuals. The information we present targets men and administrators, who will better understand the barriers to advocacy, learn best-practices of effective advocacy, and hear first-hand experiences of successful advocacy. BackgroundMany factors -systemic and non-systemic, conscious and unconscious, policy and climate -can negatively impact the participation of min...
