Vibrations of a beam can be described as an Euler-Bernoulli beam,or as a Rayleigh beam or as a Timoshenko beam.In this paper,we establish the existence of perio
In this paper,a reconstruction problem of the spatial dependent acoustic source from multiple frequency data is discussed.Suppose that the source function is su
In this paper,a stochastic second-order two-scale(SSOTS)method is proposed for predicting the non-deterministic mechanical properties of composites with random
