Design and Analysis

Design and Analysis

Design can be defined as the examination of a problem and the development of its solution. Analysis involves the application of scientific analytic principles and processes to reveal the properties and state of a system, device or mechanism under study. The processes can be applied to existing systems with existing problems, or to the creation of completely new systems from concept.

Useful information is presented in article format. Each article is a manageable size and is divided into clear sections. There is no need to read them in order. The intention is that the website is used as a reference tool.

Connections / Joints

Structural and mechanical connections are the links which tie systems together. A system is only as strong as its weakest link. Investigation of major structural failures throughout history has shown that the failure commonly propagated from a connection, be it welded, bolted or otherwise. Mechanical connections or joints are inherently weaker than the parent structure and their proper design requires great care and attention.
