Lecture
This lecture explores the kinematic approach to the problem of vertical slopes, focusing on postulating a kinematic mechanism of failure, applying virtual work principles, calculating external forces and dissipated powers, and determining the upper bound of failure. The instructor discusses the conditions for stability, the concept of dilatancy, and the calculation of power dissipation along the slope. The lecture concludes with a comparison between the upper and lower bounds of failure and the potential for more accurate solutions using advanced finite element methods.
