riveted joint failures – Mechanicalinfo

Nov 02, 2011Failures of a Riveted Joint: A riveted joint may fail in the following ways : 1. Tearing of the plate at an edge. A joint may fail due to tearing of the plate at an edge as shown in Fig. This can be avoided by keeping the margin, m = 1.5d, where d is the diameter of the rivet hole. 2. Tearing of the plate across a row of rivets.

Inhibitory Effect of Gas Impurities on Hydrogen

inhibitory effect appeared in the 1000 MPa UTS material, the inhibitory effect of impurities did not appear in the 2000 MPa UTS material. To inhibit hydrogen embrittlement in the 2000 MPa UTS material, more impurities were required. It was demonstrated that the inhibitory effect of impurities is decreased by increasing the material strength.

Effect of contact anisotropy on the crushing strength of

Abstract. This work deals with the effect of the contact orientation distribution on the crushing of granular materials. At first, a simple drop weight experiment was designed in order to study the effect of the location of three contact edges on the fracture pattern and the strength of a model cylindrical particle.

Mechanical Properties and Crushing Mechanism of Reef Coral

Sep 28, 2020The results show that the incorporation of standard sand reduces the shear strength of coral sand, and the effect is most apparent when the 0.3–0.5 mm particles are replaced. As the water content increases, the cohesion of the coral sand mixture decreases, whereas the internal friction angle first increases and then decreases.
