摘要： A method is provided for calculating gaseous diffusion and oxidation evolution of a ceramic matrix composite (CMC) structure, which includes determining temperature and load distribution in a structural member; determining matrix crack distribution in the structure; establishing an equivalent diffusion coefficient model of a fiber bundle scale to predict a gas flow channel in a fiber bundle: averaging a total amount of gaseous diffusion in the channel to establish the equivalent diffusion coefficient model of the fiber bundle composite scale related to the matrix crack distribution; establishing a representative volume element (RVE) model; establishing an equivalent diffusion coefficient model of a RVE scale; calculating the distribution of the gas concentration and oxidation products in the structure; calculating a growth thickness of an oxide at cracks and pores in each element; and updating sealing conditions of the gas channel, and calculating a new equivalent diffusion coefficient field and the distribution of the oxidation products again.

摘要： Disclosed is an improved system and method to evaluate the status of a material. The system and method are operative to identify flaws and measure the erosion profile and thickness of different materials, including refractory materials, using electromagnetic waves. The system is designed to reduce a plurality of reflections, associated with the propagation of electromagnetic waves launched into the material under evaluation, by a sufficient extent so as to enable detection of electromagnetic waves of interest reflected from remote discontinuities of the material. Furthermore, the system and method utilize a configuration and signal processing techniques that reduce clutter and enable the isolation of electromagnetic waves of interest. Moreover, the launcher is impedance matched to the material under evaluation, and the feeding mechanism is designed to mitigate multiple reflection effects to further suppress clutter.

摘要： Provided are a sintered ceramic and a ceramic sphere which are inhibited from suffering surface peeling due to fatigue resulting from repetitions of loading and can attain an improvement in dimensional accuracy when subjected to surface processing and which have excellent wear resistance and durability. A ceramic-sphere inspection device is also provided with which a ceramic sphere is inspected for a flaw present in the surface layer and for snow flakes without destroying the ceramic sphere. The device is a ceramic-sphere inspection device (100) in which a ceramic sphere (S) is rotatably supported in a given position and illuminating light emitted from a light projector (110) is detected with a light receiver (120) to evaluate the state of the inner part of the surface layer, and has been configured so that the light receiver (120) does not detect the light emitted from the light projector (110) and reflected at the surface of the ceramic sphere.

摘要： Plural of virtual curved surface solids, each of which is a curved surface solid formed by a combination of plural of virtual spheres, is placed so as to fill in space voxels, referring to porous-body data in which positional information is associated with voxel-type information (step S100). Information regarding a flow rate for each space voxel when a fluid passes through a porous body is derived by executing a fluid analysis based on the porous-body data (step S110). A flow-rate-weighted mean diameter Ru, which is a weighted average obtained by weighting an equivalent diameter R′i for each virtual curved surface solid with a volume Vi and an average flow rate Ui for each virtual curved surface solid, is derived based an information regarding the virtual curved surface solids and information regarding the flow rate for each space voxel (step S120).

摘要： A ceramic armor system with built-in conductive circuit attached to a ceramic component. The conductive circuit can be accessed by a user at contacts provided in the system. The circuit is arranged so that damage such as cracks that occurs within the ceramic component can propagate into the conductive material forming the circuit and thereby cause a rupture in the conductive circuit. An electrical probe such as an ohmmeter is used to measure the conductive circuit resistance that is then checked against an expected value. The results are used to determine if the ceramic armor component is in operable condition.
