D6BR-C

Components often seen in the works. The common features of this kind of joint feature of the members are that the size is equal to the two sides of the component, and the direction is opposite, the action line is close and the external force is perpendicular to the rod axis. In such under the action of external force, bar the main deformation is: to force between the cross section of the M - m as the interface. The components of the two part along the surface relative dislocation. This form of deformation is called the shear, the cross section m - M is called the shear plane, the shear plane is parallel to the direction of the force. When the external force is large enough, the component will be cut off along the shear plane. Only a shear plane, known as a single shear, while the member under compression, both sides also by other components of the extrusion, the phenomenon of local surface compression is called extrusion. If the pressure is large, the contact surface of the local area will occur significantly plastic deformation, resulting in the structure can not be used normally, this phenomenon is called extrusion damage. In addition to shear and extrusion, the connector is often accompanied by other forms of deformation. For example, bending or stretching deformation. But because of the relative shear and extrusion deformation, the main reason is not considered. This type of deformation is caused by the size of the same direction, in the opposite direction, the action line is parallel to each other, the performance of the two part of the shear rod along the direction of external force is relatively wrong. Commonly used in mechanical fasteners, such as bolts, pins, keys have shear deformation.
