abstract = {In this paper, by using the mountain pass lemma and the skill of truncation function, we investigate the existence and concentration phenomenon of nontrivial weak solutions for a class of elastic beam differential equation with two parameters    λ and    μ when the nonlinear term satisfies some growth conditions only near the origin. In particular, we obtain a concrete lower bound of the parameter    λ, and analyze the relationship between    λ and    μ. In the end, we investigate the concentration phenomenon of solutions when    μ  →  0, and obtain a specific lower bound of the parameter    λ which is independent of    μ.}
