This study analyzes the free vibration, forced vibration, resonance, and stress wave propagation of orthotropic sandwich plates made of functionally graded materials (FGMs). Dynamic analyses are conducted using a mesh-free method based on first-order shear deformation theory and the shape functions constructed using moving least squares approximation. The sandwich plates are rested on a Pastern...

BACKGROUND/PURPOSE Existing skin mechanical testing devices focus on measuring skin elasticity and are not tailored to assess the dynamic behavior of skin. Additionally, the mathematical techniques used in existing devices are often not optimal. METHODS A new dynamic mechanical device that measures the linear dynamics of skin was developed and tested. The mechanical properties of skin were ev...

We apply linear relation analysis CH78,HPR97] to the ver-iication of declarative synchronous programs Hal98]. In this approach, state partitioning plays an important role: on one hand the precision of the results highly depends on the neness of the partitioning; on the other hand, a too much detailed partitioning may result in an exponential explosion of the analysis. In this paper, we propose ...

Structural walls commonly used as efficient structural elements to resist lateral and vertical loads. Diverse performance of bearing wall system in past earthquakes, motivates investigation on the adequacy of current seismic design provision for these walls. This study considers seismic performance of model walls of bearing wall and building frame systems designed as ordinary and special struct...
