1.1 This test method covers the measurement of the effective surface roughness of an opaque reflecting surface as determined by the total integrated light scattering (TIS).

1.2 Applications:

1.2.1 This test method...

1.1 This specification covers wrought carbon steel sleeve type pipe couplings suitable for joining carbon steel pipes.

1.2 Type I couplings are intended for use on all schedules of pipe where the pipe wall thickness does not exceed the wall thickness of standard weight pipe. Type II coupl...

A higher-order theory for laminated composite beams is used to study the free vibration of laminated composite beams, and the differential quadrature method is employed to obtain the numerical solution of the governing differential equations. Free vibration analysis of beams with rectangular cross-s...

Real mode theory in configuration space has shown that the mode acceleration method converges faster than the mode displacement method. This paper demonstrates a similar conclusion in the state space. Some new expressions on modal parameter matrices were set up first. A generalized velocity method (...

The precision of the laser gyro used in tactical missiles is poor because of dithering frequency, actuating by vibration, shock and overload in dynamical environment. This paper introduces the transfer matrix method of the multibody system (MSTMM), establishes the dynamic model of the laser gyro str...
