Continuing Chicone and Jacobs' work for planar Hamiltonian systems of Newton's type, in this paper we study the local bifurcation of critical periods near a nondegenerate center of the cubic Liénard equation with cubic damping and prove that at most 2 local critical periods can be produced from eith
