Sumario:This thesis serves as an introduction to the qualitative theory of non-smooth dynamics, particularly focusing on codimension-1 bifurcations in planar systems. It includes a review of canonical forms for codimension-1 vector fields as well as the proof of their existence, a demonstration of the existence of the hyperbolic limit cycle in the invisible fold-fold for $\alpha>0$, and a comparative study of the invisible fold-fold bifurcation with the classical Andronov-Hopf bifurcation. In the assessment of the limit cycle's stability, it is been adapted a method from classical dynamical systems developed in \cite{andronov1971theory}.
