The Johnson Cook Material Model in the ANSYS Workbench LS-DYNA Product (February 2015). This presentation content includes a recording of DRD’s webinar on this topic, which we conducted February 20, 2015. It also includes a soft copy in pdf format of the presentation as well as the ANSYS LS-DYNA model and the spreadsheet for calculating Johnson Cook material constants discussed in the webinar. This webinar focuses on a specific nonlinear elastic-plastic and failure model in Workbench LS-DYNA called the Johnson Cook model. Johnson Cook predicts material failure such that the failure strain is dependent on the triaxial state of stress. Johnson Cook is useful when the finite element model needs to predict structural behavior after material failure has occurred. A common example of Johnson Cook is automotive crash simulation, however, there are many other applications for the Johnson Cook material model.

DRD Technology ANSYS R15 Update Webinar Part 1: Meshing (September 2014). This presentation content includes a recording of DRD’s webinar on this topic, which we conducted July 24, 2014. It also includes a soft copy in pdf format of the presentation. This webinar focuses on meshing. Meshing is one of the most impactful areas of improvement in ANSYS R15 because practically all ANSYS users create their meshes in ANSYS. ANSYS R15 creates meshes faster, requires less computer memory, and completes meshes more reliably than previous ANSYS versions. The multizone and patch independent meshers at ANSYS R15 are particularly faster and more reliable than in previous versions. Parallel part meshing, introduced at ANSYS R15, enables customers to mesh assemblies much faster than in previous releases by using all available computer cores without the requirement of additional licensing. The ANSYS R15 Meshing webinar agenda is as follows:

  • Introduction to DRD and ANSYS, Inc.
  • Advantages of Brick Meshes Over Tetrahedron Meshes
  • Multizone Mesher
  • Patch Independent Mesher
  • Parallel Part Meshing
