ANSYS Workbench | Compression Test of Concrete Cylinder Using SOLID65 | DP & Von Mises Yield Models

In ANSYS Workbench, defining uniaxial tensile strength for Solid65 elements can lead to instability. To prevent this, it is recommended to set UnTensSt (compressive strength) = -1. This ensures that ANSYS ignores crack-related effects, allowing concrete’s compressive behavior to be modeled as a ductile material using plasticity models like Von Mises or Drucker-Prager (DP). While these models do not perfectly capture brittle failure behavior, they remain a practical alternative for specific simulations. 📌 What You’ll Learn in This Tutorial: ✅ How to define a concrete material model using Solid65 elements in ANSYS ✅ How to apply the Multilinear Isotropic Hardening (MISO) and DP model for Solid65 elements ✅ Implementing ANSYS APDL code for concrete compression modeling 📢 Like, subscribe, and leave a comment if you have any questions! 🚀 #ANSYS #ConcreteModeling #Solid65 #DruckerPrager #VonMises #APDL #FEA #StructuralAnalysis #FiniteElementAnalysis 📌 Concrete Material Modeling and ANSYS Implementation Using SOLID65 Elements and APDL Code: https://tranhan1405.github.io/posts/2... 📌 Download ANSYS WB Model (ANSYS 2023R2): 🔗https://drive.google.com/drive/folder...
