The concern of this paper is the large amplitude free vibration of strongly non-linear oscillators u¨+ mu + o1u 2 u¨+ o2uu˙2 + o2u 3 = 0, where m =1, 0, or -1, o1 and o2 are positive parameters which may be arbitrarily large, and u(t) may be of order unity. Approximate analytical solutions for the p
