With advanced composites increasing replacing traditional metallic materials, the material inhomogeneity and inherent anisotropy of such materials lead to not only new attributes for aerospace structures, but also introduce new technology to damage tolerant design and analysis. The deleterious effects of changes in material properties and initiation and growth of structural damage must be addre...
Abstract The paper deals with the identification of the delamination in composites on the basis of the information for the displacements from the surfaces of damaged bodies. The identification of the active delamination region on the interface between two layers of given composite material is a non-linear programming problem that consists of minimization of a Kohn-Vogelius type of functional [3...
Layered borosilicate zeolite precursor ERB-1P (Si/B = 11) is delaminated via isomorphous substitution of Al for B using a simple aqueous Al(NO3)3 treatment. Characterization by PXRD shows loss of long-range order, and TEM demonstrates transformation of rectilinear layers in the precursor to single and curved layers in the delaminated material. N2 physisorption and base titration confirm the exp...
