Joint design basic principles

The treatment of these issues will be discussed jointly with the health, safety and environment (HSE) departments within the company and with the process and facilities engineers, and their treatment should be designed in conjunction with an environmental impact assessment. Some of the important basic principles for waste management are to ... 

The basic principles of adhesive joint design are well known and various standard configurations are available. Irrespective of joint geometry, the basic design criteria are the same. They are ... 

This book also takes into account Billet s [15] experimental data on the hydraulic behaviour of packed columns for the development of a new method for the standard presentation of the fluid dynamics of columns with any type of packing design. The basic principles of the method for determining the separation efficiencies of packed columns have already been publicised in joint presentations and individual publications by the author and Billet [16-18]. 

Although designs may vary sli tly there are basic principles that must be followed to ensure a trouble-free fife for the expansion joint. For example, to avoid differential thermal expansion at the connecting flanges, both flanges must be made... 

When a complex joint is to be introduced in a structure, the ideal situation is to test that specific joint. However, this approach is very expensive. Before real joints or prototypes are built, the designer should first come up with a good prediction of the failure load based, among other things, on the basic mechanical properties of the adhesive. The basic properties can mean the elastic properties, such as the Young s modulus and the Poisson s ratio in case the analysis is linear elastic. However, for the more realistic theoretical methods that take into account the nonlinear behavior of the adhesive, the yield stress, the ultimate stress, and the failure strain are necessary. The stress-strain curve of adhesives is necessary for designing adhesive joints in order to compute the stress distribution and apply a suitable failure criterion based on continuum mechanics principles.
