This paper investigates the existence of positive solutions for a class of singular 𝑝-Laplacian fourth-order differential equations with integral boundary conditions. By using the fixed point theory in cones, explicit range for 𝜆 and 𝜇 is derived such that for any 𝜆 and 𝜇 lie in their respective interval, the existence of at least one positive solution to the boundary value system is guaranteed.
