Plasticity, limit analysis, and limiting equilibrium

  • C. R. Scott


A system of surface and body forces applied to a body will cause changes in the stresses and strains within it. The changes in strain will usually be partly elastic and immediately recoverable, but may also result in part from irrecoverable plastic yield. As the forces increase, a growing part of the body may reach the limit of its shear strength. Once this part is sufficiently extensive to form an unstable mechanism, unlimited yield will occur. This will continue as long as the forces can be maintained in the face of the changing geometry of the body. This unlimited yield is called collapse, and the system of forces which will produce it is called the collapse load.
