Leighton et al. [38] demonstrated that Gaussian fit data is not accurate for modelling any engineered surfaces and went on to demonstrate [39] that early running of the surfaces results in a gradual transition which significantly changes the surface topography, load carrying capacity and friction.
Airbag launching refers to a method to launch vessels with marine air bags. It is a methodology for ship launching utilizing air bags. [1]The Xiao Qinghe shipyard launched a tank barge with marine airbags on January 20, 1981, and it is known as the first use of marine airbags.
The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.
While any pressure angle can be manufactured, the most common stock gears have a 20° pressure angle, with 14½° and 25° pressure angle gears being much less common. [4] Increasing the pressure angle increases the width of the base of the gear tooth, leading to greater strength and load carrying capacity.
In general, exact solutions for cantilever plates using plate theory are quite involved and few exact solutions can be found in the literature. Reissner and Stein [ 7 ] provide a simplified theory for cantilever plates that is an improvement over older theories such as Saint-Venant plate theory.
The Statnamic load test is a type of test for assessing the load-carrying capacity of deep foundations which is faster and less expensive than the static load test.The Statnamic test was conceived in 1985, with the first prototype tests carried out in 1988 through collaboration between Berminghammer Foundation Equipment of Canada and TNO Building Research of the Netherlands.
Hydraulic, electromagnetic or pneumatic actuators are used to apply loads to the structure, either directly or through the use of a whiffletree to distribute the loads. A load cell is placed inline with the actuator and is used by the load controller to control the loads into the actuator. When many actuators are used on a flexible test ...
Compressive stress (or compression) is the stress state caused by an applied load that acts to reduce the length of the material (compression member) along the axis of the applied load; it is, in other words, a stress state that causes a squeezing of the material. A simple case of compression is the uniaxial compression induced by the action of ...
