摘要： A localized fiber reinforcement places strong tensile strength fibers across a hypothetical split line near notches in beams to curtail split propagation caused by cross-grain tension that may otherwise significantly reduce the strength of a beam used as a spanning member. An adhesive coated patch may be applied after a notch is cut in the beam or fibers may be attached to a beam at a factory near the location of an anticipated notching.

摘要翻译： 局部纤维增强件将强拉伸强度的纤维穿过横梁上的凹口附近的假想分裂线，以减少由横向晶粒张力引起的分裂传播，否则可能会显着降低用作跨越构件的梁的强度。 在光束切割槽口之后，可以施加粘合剂涂覆的贴片，或者纤维可以在预期开槽位置附近的工厂连接到梁上。

摘要： A method and apparatus are provided for the determination of a surface area of a fastener, such as a threaded fastener. Specifically, an image of the fastener is acquired, and the image is separated into at least two regions, for instance three regions, and the surface area of each region is determined. The surface areas determined for each region are summed to determine the surface area of the fastener.
摘要翻译： 提供了一种用于确定诸如螺纹紧固件的紧固件的表面积的方法和装置。 具体地说，获得紧固件的图像，并且将图像分成至少两个区域，例如三个区域，并且确定每个区域的表面积。 将针对每个区域确定的表面积相加以确定紧固件的表面积。
