The manufactur errors of flexure hinge will influence the performances,so for reducing the flexible hinge on the performance of the sensitivity of manufacturing errors,the relation among design parameters of corner-filleted flexure hinge and manufacture error was founded by using multi-variable function of Taylor series expansion.

Dynamic modelling and analysis of a rotating flexible beam;

Stability and Hopf bifurcation analysis of axially narrow-band random oscillating flexible beams;

Large deflection analysis of flexible beams by integration methods;

Studies on bearing capacity calculating method of local compression for masonry of flexible pad-stone;

Due to the characteristics and difficulties of subgrade longitudinal cracks, a flexible beam (FB) technique is put forward.

Synthesized the domestic and international current result,the paper presents the geogrids and flexible beams treating technology to ravel out the distress of the longitudinal cracks.
