3rd International Conference on Buckling and Postbuckling Behavior of Composite Laminated Shell Structures with DESICOS Workshop
25-27 March, 2015
List of DESICOS participants:

Technical University Delft
Leibniz University Hanover
Private University of Applied Science Göttingen
Politecnico di Milano
Riga Technical University
RWTH Aachen
Technion
CRC-ACS - Cooperative Research Centre for Advanced Composite Structures
Co-ordinator:
German Aerospace Center (DLR),
Institute of Composite Structures and Adaptive Systems,
Braunschweig, Germany
Prof. Richard Degenhardt
Conference Place:
Technical University of Braunschweig
Pockelsstrasse, Braunschweig, Germany
Aim of the conference and workshop:
Conference and workshop are primarily organised as the final events of the running EU project DESICOS demonstrating its results. The scientific community and industry in general are invited to attend. Both events aim to promote discussion and exchange of information between scientists and engineers in the field of buckling, postbuckling and collapse behaviour of composite structures. The conference aims at presenting scientific achievements from the DESICOS project. In addition, papers with recent results on the same topic but from outside the project are as
well accepted. Within the workshop new fast design tools developed by DESICOS, are presented and demonstrated.
History:
The present conference follows the two conferences from the past:
1st Int. Conference on Buckling and Postbuckling Behaviour of Composite Laminated Shell Structures Eilat, Israel, 1-2 March 2004, demonstrating results from the EU project POSICOSS, www.cocomat.de
.
2nd Int. Conference on Buckling and Postbuckling Behaviour of Composite Laminated Shell Structures Braunschweig, Germany, 5-7 September 2008, demonstrating results from the EU project COCOMAT, www.cocomat.de.
Topics:
New achievements in the following topics on buckling, postbuckling
and collapse behaviour of composite laminated shell structures are presented:
• Influence of imperfections
• Experimental methods and results
• Design guidelines
• Advanced finite element tools for certification
• Fast design tools
• Degradation models
• Failure criteria
• Structural optimisation
All topics shall focus on various Composite Laminated Shell
Structures under different states of loading
Description of the EU project DESICOS:
The running EU project DESICOS (New Robust DESIgn Guideline for Imperfection-Sensitive COmposite launcher Structures) is a Level 1 Project within the 7th Framework Programme. It started February 2012 and will be finished in March 2015.
DESICOS aims to exploit considerable reserves in the capacities of imperfection-sensitive composite launcher structures by applying the Single Perturbation Load Approach (SPLA), which assumes that a large enough disturbing load leads to the worst realistic geometric imperfection, combined with a Specific Stochastic Approach to take into account load imperfection, thickness imperfection, etc. Currently, imperfection-sensitive shell structures prone to buckling are designed according to the NASA SP 8007 guideline using the conservative lower bound curve.The guideline dates from 1968, and the structural behaviour of composite material is not considered appropriately, in particular since the imperfection sensitivity and the buckling load of shells made from such materials depend on the lay-up design. NASA SP 8007 design guidelines allow designing only so-called "blackmetal" structures. Therefore, there is a high need for a new precise and fast design and testing approach.
The project results comprise an experimental database, new design approaches for imperfection-sensitive structures and new design recommendations.
