and then form a wedge-shaped compression-shear fracture zone at the two loading ends. (2) Shear-tension crack formation mechanism and semicircle bending fracture mechanism In the process of the disk ...

The course covers: free body diagrams; equilibrium equations; statically determinate systems; method of joints and method of sections; concept of stress and strain; axial and shear force and bending ...

Water is ubiquitous and seemingly ordinary, possessing no distinct color or odor. Though we often take water for granted, it ...

Otherwise, disk abnormality should be attributed to an automobile accident only if it is of a type not normally seen in the aging process, or if there is neural compression on MRI and appropriate ...

Forces act on materials all the time - even if a material appears stationary it still has a force acting on it. There are five terms used to describe what type of force can act on a material: ...

The erosion threshold of sand-mud mixtures is investigated by analyzing the momentum balance of a sand particle or a mud parcel in the mixture bed surface, and a formula for the critical shear stress ...

Unlike other SEAs that use compression springs, this design employs a torsion spring. The mechanism and the working principle of the linear SEA are presented, along with an analysis of the custom ...
