Blow-up Phenomena for a Semilinear Fourth-Order Wave Equation with Time-varying Source and Strain Terms at High Energy Level
摘要
Abstract
This paper is concerned with the initial boundary value problem for a semilinear fourth-order wave equation with time-varying source and nonlinear strain terms under Dirichlet or Navier bound-ary condition.By utilizing the invariance of unstable set,contradiction argument and concavity method,we prove that the solution blows up in finite time at high energy level.关键词
