Experimental Results of Helical Metal Expansion Joints Fabrication

An algebraic study of linkages with helical joints

Methods from algebra and algebraic geometry have been used in various ways to study linkages in kinematics. These methods have failed so far for the study of linkages with helical joints (joints with screw motion), because of the presence of some non-algebraic relations. In this article, we explore a delicate reduction of some analytic equations in kinematics to algebraic questions via a theore...

Experimental Studies on Vibration Testing of Pipe Joints using Metal Gaskets

Pipe joints have been widely utilized in industrial plants, where dynamic load of vibration is considerably harmful for sealing performance. However, there is a lock of design codes and experimental procedures developed for vibration testing of pipe joints. This paper proposes an experimental setup for testing of pipe joints, which use metal gaskets, in vibratory conditions. Also, a flexible pi...

Failure of Adhesively Bonded Joints. Analysis of Experimental Results by Nominal and Local Approaches

The failure in structural adhesively bonded lap joints can be analyzed following different approaches: using a nominal stress state typically given by Strength of Material models, a local singular stress state induced at the mutimaterial corners of the joint, or using cohesive constitutive laws for the adhesive layer or other damage progression models. The aim of this paper is to analyze the su...
