Simulation of structural vibrations using Voronoi-cell lattice models
Dynamic failure behaviors of quasi-brittle materials and structures have been simulated using the Voronoi-cell lattice model (VCLM) under various loading rates. However, such loadings are rather limited to mon...

Evaluation of dynamic tensile strength of concrete using lattice-based simulations of spalling tests
The mechanical properties and failure modes of concrete are affected by strain rate. Therefore, various experimental methods have been used to quantify the strain-rate dependency of concrete properties, such a...

Rotordynamic analysis and operation test of the power turbine with the concept of the Lee diagram
Rotordynamic analysis in complex coordinates has many advantages. Especially, the Lee diagram, with the concept of the infinity norm in directional frequency response matrix, can an effective design tool for r...

Flame extinction in interacting CO-air and syngas-air premixed flames
Chemical interaction on flame extinction in downstream interaction of syngas-air and CO-air premixed flames was investigated. Flame stability diagrams map** the extinction limits for various fuel concentrati...

Effects of microstructure on flexural strength of biomorphic C/SiC composites
Biomorphic C/SiC composites were fabricated from different kinds of wood by liquid silicon infiltration (LSI) following a two-step process. In the first-step, the wood is converted into carbon preforms by pyro...
