TY - JOUR AU - Liu, Jian AU - Yu, Wenguang PY - 2021 DA - 2021/03/31 TI - Two solutions to Kirchhoff-type fourth-order implusive elastic beam equations JO - Boundary Value Problems SP - 38 VL - 2021 IS - 1 AB - In this paper, the existence of two solutions for superlinear fourth-order impulsive elastic beam equations is obtained. We get two theorems via variational methods and corresponding two-critical-point theorems. Combining with the Newton-iterative method, an example is presented to illustrate the value of the obtained theorems.
