THREE DIMENSIONAL ANALYSIS OF BOLTED JOINT MEMBER STIFFNESS USING FRUSTA METHOD

Abstract

Joint member stiffness has a great influence for both static and dynamic loading for a safe mechanical design of many types of bolted- jointed member connections. A three dimensional mathematical model for the jointed member system has been derived. This work provides a simple mathematical technique used to calculate different types a jointed member stiffness of a bolted connections. A finite element analysis is performed for the bolted joint and the model is used to predict stress field for a Grey Cast iron andaluminum alloy. Joint member stiffness is presented against member aspect ratio indimensionless form. Results show good agreement as compared with those of usedtechniques of Montosh and Marschke
