Abstract

"This thesis deals with the strength of a bolted joint which is subjected to tensile and bending loads. The purpose of this investigation was to derive expressions for the stresses developed in the bolts and the load producing separation of the joint.

A laboratory study of a flange coupling was made and the behaviour of flange bolts under different clamping forces was studied in tension and bending tests. The strain in the bolt was measured by mounting the strain gages on the shank of the bolt. From this, a graph of applied load versus strain in the bolt was plotted. The load producing separation of the flanges was determined from the graph and was used in deriving the formula for the prediction of load which will loosen the joint.

The following factors will influence the strength of the flange coupling:-

(i) Initial clamping force on the bolts.

(ii) Thickness of the flange.

(iii) Number of bolts.

(iv) Diameter of the bolts. (v) Diameter of the flange.

(vi) Material and thickness of the gasket.

The previous investigation of Mr. Vijay Rastogi* deals with the first three factors and it is hoped that the reader is familiar with his thesis. The author has made an attempt to investigate the remaining factors which will adequately supplement the analysis of flange coupling"--Abstract, pages 2-3.
