ESAComp meets challenging marine applications
In this article we learn about ESAComp's role in the design-development of a carbon composite RIB "Rigid-hulled Inflatable Boat", the latest project from Dr. Luca Olivari, a naval architect, founder and owner of the Italian company Olivari Composites Engineering which specializes in engineering of composite structures. With their long experience in motorboats and sailboats structural engineering, Olivari is involved in the realization of a vast number of racing and cruising yachts. Read more...
Meet Componeering at JEC Europe 2015
JEC Europe Composites Show, Paris, March 10-11-12, 2015
- Throughout the show, drop by our stand for a look at ESAComp in action with our engineers.
- Join us for our daily Technical Briefing, each day at 11:00-11:20, where we will talk through examples of ESAComp enhanced capabilities for the design and analysis of composites structures.
- See how ESAComp interfaces with ComposicaD filament winding simulation software to provide design and analysis of composite overwrapped pressure vessels (COPV).
- For HyperWorks users, check out the interface enabling ESAComp assisted post-processing.
We're an active member of Altair Partner Alliance, find us together with Altair Engineering in Hall 7.3 on Stand S18. See Floor Plan...
Thin-walled cylinders are sensitive to imperfections
Decreased buckling loads and geometrical imperfections are closely related for thin-walled cylinders. Geometrical imperfections have been demonstrated to have clearly the highest influence on the buckling load when compared to, for example, the effect of thickness variations, stress variations, and boundary stiffness. The real imperfections are often unknown, but in the design process the influence of the imperfections has to be taken into account properly to achieve a safe structure. Read more...
Quick and clean technology for composite cylinder stability analysis
A set of thin-walled cylindrical shells (radius-to-thickness ratio of 160-500) under different loading conditions have been studied for structural stability with ESAComp using different mesh densities. Comparison has been made to results from literature references. Based on this study, guidelines for the selection of the element mesh density have been set. Read more...
Preliminary design of a wing spar bonded joint
Fast tools such as the ESAComp module for bonded joints can be very efficient in the preliminary design of various joint configurations. In this example we consider a tip loaded wing of a small aircraft or wind turbine blade. The wing spar carries a constant in-plane shear (Nxy), which needs to be transferred from the joint laminates to the shear web. Read more...
