We hope that our web site provides a great deal of valuable technical information, which is available to anyone who visits our web site. The technical materials on this page, however, are intended only for DRD's customers, and are, therefore, password protected. We provide these materials to our customers as a benefit for doing business with DRD, and at our discretion we provide them to selected DRD friends and associates.

The topics on this page are intended for engineers who are interested in highly technical and detailed information on ANSYS. These topics contain information, which is not readily available to ANSYS users through standard documentation and training courses. For example, some topics provide information on ANSYS capabilities that are under development or are not documented.

Fracture Mechanics Capabilities in ANSYS Mechanical Enterprise (February 2017). DRD conducted this fracture mechanics webinar February 09, 2017. This webinar provides a comprehensive overview of the fracture mechanics capabilities in ANSYS Mechanical Enterprise at ANSYS 17.

Engineers frequently need to answer the questions: 

  • Will the crack in my structure grow? 
  • Will the crack grow and then arrest, or will the crack lead to a complete part fracture? 
  • How long and how many load cycles will the structure last before a compete part fracture occurs? 

This webinar provides a very concise overview of linear elastic and elastic-plastic fracture mechanics. Then we proceed to show demonstrations of crack models in ANSYS including elliptical, pre-meshed, and arbitrary cracks. The webinar also covers postprocessing of ANSYS fracture mechanics models and the calculation of fracture entities such as stress intensity factor (SIF), J integral, and energy release rate. DRD also demonstrates ANSYS' ability to automatically grow cracks using the XFEM technique.

Filament Wound Composites Engineering Simulation Featuring ANSYS Composite PrepPost (March 18, 2016). This content includes a recording of DRD’s webinar conducted March 18, 2016, and it provides an overview of how ANSYS Composite PrepPost (ACP) may be used to model filament wound composite structures. ACP is a module of ANSYS that has been recently folded into the ANSYS Mechanical Enterprise and ANSYS Mechanical Enterprise PrepPost products. ACP provides a highly automated preprocessing and postprocesing environment to develop and evaluate composite finite element models in ANSYS.

DRD commences this presentation with short videos showing the filament winding process. A DRD Applications Engineer then develops in ACP and solves in ANSYS Mechanical a closed end filament wound composite pressure vessel structure starting from a mandrel surface as is typical in the manufacturing of pressure vessels and rocket motor casings. The demonstration includes exporting the composite part to SolidWorks CAD for creating metal parts that fit the contours of the composite part created in ACP.

Filament winding is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks). The process involves winding filaments under tension over a rotating mandrel.

Introduction to ANSYS Composite PrepPost (March 15, 2016). This content includes a recording of DRD’s webinar conducted March 15, 2016, and it provides an introduction to the ANSYS Composite PrepPost (ACP) module in the ANSYS Mechanical Enterprise product. ACP is a module of ANSYS that has been recently folded into the ANSYS Mechanical Enterprise and ANSYS Mechanical Enterprise PrepPost products. ACP provides a highly automated preprocessing and postprocesing environment to develop and evaluate composite finite element models in ANSYS.

Engineering layered composites involves complex definitions that include numerous layers, materials, thicknesses and orientations. The engineering challenge is to predict how well the finished product will perform under real-world working conditions. Simulation is ideal for this when considering stresses and deformations as well as a range of failure criteria. ACP provides all necessary functionalities for finite element analysis of layered composite structures. You can choose to work with either shell theory (thin-composites) or move to modeling solid composites in the case of thicker parts.

The webinar provides a short presentation on ACP followed by a demonstration. In the demonstration a DRD Applications Engineer defines the laminate for a composite part, models the part in an assembly containing metal parts, and postprocesses the model results using a combination of ANSYS Mechanical and ACP.
