Analysis of a bolted composite joint with ply failure done in Abaqus

Posted by Nikolaos Mavrodontis on Nov 10, 2020 9:00:00 AM

In this blog post, we will be showing an analysis of a bolted joint. The joint comprises of two flat plates that are made of carbon fiber reinforced polymer material (CFRP). Both plates have the same 8 ply layup (symmetric), and have been modelled with stacked continuum shell elements. Ply failure modelling has been considered in terms of Hashin failure criterion damage initiation and fracture energy damage evolution.

Modeling Bolted Connections with Abaqus FEA

Posted by Nikolaos Mavrodontis on Sep 18, 2018 9:15:15 AM

In this blog post, we will be discussing about the different methods in modeling bolted connections with Abaqus FEA. At the last section of the post,we will be showcasing a bolted connection, incorporating a pretensioned bolt. Flanged connections are used extensively in most engineering disciplines. They provide a way of interconnecting  various (metallic, plastic etc.) components and their design is often critical for the strength of various components (e.g. bolt strength) and sealing of the assembly.
