In this paper, we establish an upper bound and sharp lower bounds on the minimum $M$-eigenvalue of elasticity $Z$-tensors without irreducible conditions. Based on the lower bound estimations for the minimum $M$-eigenvalue, we provide some checkable sufficient conditions for the strong ellipticity. Numerical examples are given to show the efficiency of the proposed results.
