On Hermite-Hadamard Type Integral Inequalities for Functions Whose Second Derivative are nonconvex

In this paper, we extend some estimates of the right hand side of a Hermite- Hadamard type inequality for nonconvex functions whose second derivatives absolute values are \phi-convex, log-\phi-convex, and quasi-\phi-convex.
