A Python script used to convert the input file generated by ABAQUS for VABS, a detailed step-by-step instruction using ABAQUS CAE to generate a simple beam section (composite anisotropic pipe) is also given. Python scripts for generating more complex sections such as real...
Assessing VABS against ABAQUS Beam Section Generate
27 May 2015 | | Contributor(s):: Su Tian, Wenbin Yu
We did a case study for a composite beam using VABS and ABAQUS beam section generate capability and compared with detailed 3D FEA analysis. The conclusion is that VABS can reproduce the detailed 3D FEA analysis at an efficiency much faster than ABAQUS beam capability. The accuracy of ABAQUS beam...
