    Microstructure and Mechanical Properties of Sm1-xSrxCo0.2Fe0.8O3

    The room temperature mechanical properties of a mixed conducting perovskite Sm1?xSrxCo0.2Fe0.8O3 (x = 0.2 to 0.8) were examined. Density, crystal phase, and microstructure were characterized. It was found that th...

    Mechanical properties of alkaline earth-doped lanthanum gallate

    Lanthanum gallate doped with alkaline earths was prepared from combustion-synthesized powders. Mechanical properties of the doped gallates were evaluated as a function of composition and temperature. The inden...

    Residual stress-induced spontaneous microcracking in α-SiC platelet Al2O3 composites

    The micromechanical stresses associated with hexagonal (6H) α-SiC platelets within a fine-grained alumina matrix were calculated using an Eshelby approach. The stresses within and around the interface of SiC p...

    Fracture toughness of macro-defect-free cement using small crack techniques

    The fracture toughness of a macro-defect-free (MDF) cement was calculated from two measurement techniques: (1) indentation-strength method and (2) fracture surface analysis (FSA). It was found that the indenta...

    Two classes of boundary type cubature formulas with algebraic precision

    Here presented are two classes of multivariate numerical integration formulas that make use of merely boundary points as evaluation points. Some special boundary type formulas are constructed as illustrative e...

    The Dimensions of Bivariate Spline Spaces Over Triangulations

    Let D be a polygon and Δ be a triangulation of D such that any vertex of a triangle does not lie in the interior (open line segment) of any edge of another triangle. Denoted by Pk, the collection of all polynomia...
