This note provides a variational description of the mechanical e¤ects of flexural sti¤ening of a 2D plate glued to an elastic-brittle or an elastic-plastic reinforcement. The reinforce- ment is assumed to be linear elastic outside possible free plastic yield lines or free crack. Explicit Euler equations and a compliance identity are shown for the reinforcement of a 1D beam.-

Abstract
This note provides a variational description of the mechanical e¤ects of flexural sti¤ening of a 2D plate glued to an elastic-brittle or an elastic-plastic reinforcement. The reinforce- ment is assumed to be linear elastic outside possible free plastic yield lines or free crack. Explicit Euler equations and a compliance identity are shown for the reinforcement of a 1D beam.-
