Applications

Joining of composite structural aircraft components

From the first successful flying structures up to the present time, various structural materials were used in the construction of aircraft, ranging from heavy steel, through aluminum alloys, to other metals and their alloys. For the last several years there has been a noticeable increase in the use of composite materials in the aviation industry. This is because of their properties – they are relatively light and, on the other hand, they are mechanically resistant.

Designing fl anged circular joints with a gasket

This study presents calculations of the bolted flanged joints with a gasket, used in piping systems. The method described in PN-EN 1591-1 has been adopted as the basis for calculations. Design assumptions used in the calculation method and its limitations have been discussed. The calculation algorithm for the selected flanged joints is presented.

Innovations

Preventing head cracks on bolts: a numerical approach

Cold forging, one of the oldest methods of production, is a metal forming process that is often preferred in today’s industry. In cold forging process, workpiece is formed by being exposed to press forces between two dies or tools. Moreover, high surface quality can be obtained and precise tolerances can be achieved in cold forging.

Innovative furniture fitting systems

Modern furniture connecting fittings should be versatile, mechanically durable and easy to install. In some cases they are required to provide multiple assembly/disassembly capability, to be invisible and, due to a shorter life cycle of the product, to be easily recyclable.
