ESAComp is software for the analysis and design of composite laminates and laminated structural elements. The development work was initiated by the European Space Agency (ESA/ESTEC), who envisioned open software which would combine all necessary composites analysis and design capabilities under one unified user interface. Although it originated in the aerospace field, ESAComp has been developed as a general tool for people dealing with composites, both in industry and in research. The core of the ESAComp development work was conducted under an ESA/ESTEC contract by Helsinki University of Technology and its partners. The first official release of ESAComp came out in 1998. In 2000, the development work was transferred to Componeering Inc., which also serves as software distributor and provider of ESAComp support services. ESAComp has a vast set of analysis and design capabilities for solid/sandwich laminates and for micromechanical analyses. It further includes analysis tools for structural elements: plates, stiffened panels, beams and columns, bonded and mechanical joints. Thanks to its ability to interface with widely used finite element software packages, ESAComp fits seamlessly into the design process. Last update of ESAComp web site: May 12, 2008 © Componeering Inc.
