Componeering (Helsinki, Finland) is introducing ESAComp 4.5, the latest version of its software for composite design and analysis, which includes a major new feature for composite pressure vessels. The new module uses input from the ComposicaD filament winding process simulation tool by Seifert and Skinner & Associates. The combination of ComposicaD and ESAComp is said to provide an efficient and economical way for reliable process and design simulation, design verification and manufacturing. The ESAComp structural analysis follows the winding simulation performed by ComposicaD. The analysis results, such as layer stresses, strains and failure margins, can be shown as contours over the pressure vessel geometry and further studied as through-the-thickness charts.
Also new, for HyperWorks users, ESAComp now offers a composite post-processing interface. Developed jointly with Altair Engineering, this interface reportedly allows smooth transfer of finite element analysis results to ESAComp where advanced composites failure criteria can be applied. Detailed analysis results are further returned to HyperWorks for display with the model geometry.
