ESAComp是一款适合分析和设计复合材料的软件。复合材料是一类新的合成材料，它将不同材料的特性结合在一起。例如，玻璃纤维是由聚合物基材料制成的多功能复合材料，并用玻璃纤维增强，同时又轻巧。复合材料在各种行业中都有许多应用，例如，用于建造雷达疏散战斗机，飞机零件，风力涡轮机叶片，直升机叶片，以及在航空航天工业中用于生产航空航天服装，航天飞机的船体等。要使复合材料达到所需的结果并非易事，必须对不同材料和化合物的性能进行不同的分析和研究，以达到可接受的结果。 更多信息： ESAComp软件是Componeering提供的用于简化此过程的产品。该程序能够帮助设计复合材料所用层的最基本阶段的专家，对复合材料的结构进行精确而细致的分析。该程序使用新的有限元方法进行分析，并且在这项工作中具有很高的准确性。该软件是一个独立的软件包，通过安装它，您将不需要安装其他程序。该程序还具有教育意义，因为它具有广泛的材料类型数据库，可以将其组合起来以分析组合的属性和结果。在现实世界中，这是一项昂贵且不必要的任务。该程序执行的分析范围从宏观表面，外观性能检查到复合材料的微机械分析。 Altair ESAComp 2020 Release NotesNew Features
Composite pressure vessel analysis for models exported from Cadfil
Shell based composite pressure vessel (CPV) analysis in ESAComp is now also available for users of Cadfil (
www.cadfil.com) filament winding process simulation software. Cadfil module shall be the type of Lite +. In addition, Cadfil FEA output license feature is required. Further CPV analysis possibilities are available by exporting from Cadfil to Altair OptiStruct, for which, in addition to shell export, a continuum-shell based approach for sector models is supported.
Laminate export to OptiStruct
In addition to existing PCOMP and PSHELL export, ESAComp now supports also ply based modeling using PCOMPP property, for which STACK and PLY cards are created, and zone-based modeling using PCOMPG card image.
Material export to OptiStruct
In addition to existing PSOLID (MAT9), ESAComp now supports PSOLID(MAT9ORT) using 9 engineering constants as opposed to the material property matrix.
Enhancements
Failure envelope for multiple criteria
When multiple criteria are active for a ply type, each graph in the first ply failure envelope gets labeled with the full set of active failure criteria. This prevents misunderstanding of the envelop, especially for laminates with multiple ply types.
Documentation and Demo Cases
- One example case (EC_49 Composite Pressure Vessel) has been added in “ESAComp Example Cases.pdf” to reflect the added capability to import and analyze models exported from Cadfil filament winding software to ESAComp.
- Panel analysis example was added to the Python scripting interface examples. It covers modification of a curved panel and its stiffeners as well as analysis of load response, failure, buckling and natural frequencies.
Other
- The so-called Design Tools (Laminate Evaluation and Laminate Creation) have been removed since the approach has become outdated and the tools were not fully functional. For design/trade-off studies, “hands-on approach” with the existing multiple analysis capabilities is recommended. Python scripting can be used for screening larger design spaces.
Resolved Issues
- Resolved issue with transforming out of plane shear stresses from laminate coordinate system to ply coordinate system.
- Python scripting will now report warning to batch log file when attempting load a non-existing XML file.
- Unit of imperfection amplitude in non-linear cylindrical shell analysis was not correctly converted when changing unit system.
- Resolved ESAComp freezing with beam stiffened panels, when stiffener material did not have allowables defined.
- Resolved some settings not being saved and correspondingly used in PCOMP export to OptiStruct.
- Resolved meshing issues for cylindrical shells with more stiffeners in circumference than number of elements in mesh settings.
- Numerous smaller bugs were fixed.
