Continuum Modeling of Discrete Structures with Geometric Nonlinearities
The modeling of geometrically non-linear discrete structures by an equivalent continuum is presented. The discrete-continuum analogy is developed by first isolating a unit cell of the...
Damage Detection in Periodic Structures
Nondestructive damage detection in periodic structures using continuum analogues of the discrete structure is studied. Algebraic equations relating changes in eigenfrequencies to the fractional...
