  central angle
Initial data obtained show the critical buckling pressure to vary as a power of the thickness and almost linearly with central angle.
      
Parameters examined included thickness, central angle and toroidal radius.
      
The desired functions are represented by the product of a power function of the radial coordinate and the unknown function of the central angle in the cross section.
      
The lack of 13-day periodicity in the solar 10.7 cm flux is caused by its broad central angle dependence that averages out the 13-day variations and produces nearly sinusoidal 27-day variations.
      
The critical pressure is expressed explicitly by a function of the radius of the inclusion and the central angle sublended by the half length of the crack; especially it is inversely proportional to the square root of the radius of the inclusion.

A parallel multi-step method which is suited for parallel processing for time integration in structural dynamic analysis is presented based on the transputer parallel processing system in PC computer. This method is used to analyze the dynamic response of elastic circular arch. Under rectangular uniformly-distributed pressure, tests show that the 'Speedup' is 3. 05, 'Efficiency' is 76.25% for four transputers. When the half central angle is small, the arch will freely vibrate about the position different from the original static one after the rectangular loading is finished. This is mainly because of geometric nonlinearity.

本文在基于个人计算机的transputer并行处理子母板系统上提出了一种结构动力分析中适合于并行处理的对时间域积分的多步法——并行多步法。并用此方法对两铰弹性圆拱在矩形荷载作用下的动力响应进行分析。算例表明,对于四处理器系统算法加速比可达3.05,效率为76.25%。对圆拱的分析表明,当中心角之半θ_0较小时,矩形荷载作用完后圆拱在偏离原静止状态的位置附近自由振动。这主要是由于几何非线性所致。
