Title

DYNAMIC STABILITY OF POWER LAW FG SHALLOW ARCHES: A THEORETICAL APPROACH

Pages

  0-0

Abstract

 One of the remarkable concerns in SHALLOW ARCHes’ behavior under lateral loading is snap-through, aphenomenon which can make the structure collapse or displace to another stable configuration.Introducing FUNCTIONALLY GRADED MATERIALs in recent years has led to some interesting results, forinstance, using FUNCTIONALLY GRADED MATERIALs in SHALLOW ARCHes can produce structures with favorablestability properties. In this work, we investigate DYNAMIC STABILITY of the pined-pined functionallygraded sinusoidal SHALLOW ARCH under impulsive loading. Material properties vary through the thicknessby power law function. Nonlinear governing equations are derived using Euler-Bernoulli beamassumption and equations of motion are expressed by a nonlinear differential-integral equation. Thesolution utilizes a Fourier form of response. The procedure to analyze DYNAMIC STABILITY followed hereuses total energy of the system and Lyapunov function in the phase space. We find the stable regionagainst dynamical snap-through under material properties’ variation in the thickness direction ofSHALLOW ARCH. We also proceed to find the sufficient critical load in order to make the dynamical snapthrough occur. The results are analyzed in detail and illustrated in some diagrams.
