Failure Analysis of Laptop Desk with Freecad FEM | Freecad Fem | Product Design | Stress Analysis | #Opensourcesoftware
Failure Analysis of Laptop Desk with Freecad FEM | Freecad Fem | Product Design | Stress Analysis | #Opensourcesoftware This Video shows how a real life failure of a product (laptop desk) can be modeled using FEA and identify the critical locations. The Analysis was carried out completely in Freecad FEM workbench. Freecad was used to model the geometry.The model was simplified, capturing only the necessary features to identify the critical locations, which can eventually fail. The dimensions does not represent the actual desk. Free cad allows meshing through GMSH or Netgen. For this analysis Netgen was used. Tetrahedral meshing was done with medium resolution. The material selected was ABS plastic. Material properties was chosen from FreeCad material library. A dummy load of 70N was applied (in reality the load was not instantaneous so it can be approximated as Static Load) and initially the face at the end of the legs were fixed as Boundary conditions and analyzed. The results were not as correct. As an improvement in BC the inner edges of the legs were fixed and analyzed.The results were correct and reflected the reality in identifying the critical Locations. It was observed that the horizontal movement of the leg is higher which causes high moment load to the leg and pad interface. Hence a horizontal member was added to limit the movement. However the analysis has provided a deep insight to explore other design options of the desk to improve its strength for resisting any accidental overload.

Static and Modal analysis of a Bladed Disk using GMSH and Calculix || CAE4U || Calculix || GMSH
Static and Modal analysis of a Bladed Disk using GMSH and Calculix || CAE4U || Calculix || GMSH #FEA #Calculix #StaticStuctural #Modal This video explains how to perform a Static structural and modal analysis of bladed disc using open source finite element analysis software. This geometry does not represent any actual product. This analysis was done just to show how open source finite element analysis software can be used for this kind of analysis. The analysis is essentially 3D cyclic-symmetric analysis. 30 degrees Sector model of bladed disc configuration is considered for the analysis. Uniform 2D structured mesh is used for this study. structured Quadrilateral elements were used for better performance. This analysis can be used to check the static strength,deformation and potential resonance. The analysis considered only centrifugal load. The mode shaped of a cyclic structural model is characterized by Harmonic index. The results from modal analysis can be used to construct the Campbell diagram (some time called as Safe/Interference Diagram) to check any possible resonance condition. In this case the prestress effect is not considered. For the study following open source software used, Geometric Modelling and meshing - GMSH (https://gmsh.info/#Download) Pre and post processing - CALCULIX CGX (http://www.dhondt.de) Solving - CALCULIX CCX Watch this Full Video on YouTube 👉 - https://youtu.be/aiBK7u6SE5I Hope the Video was useful, Please drop your comments and "FOLLOW" our page.

Modal Analysis of Circular Shell in Calculix | CAE4U
Modal Analysis of Circular Shell in Calculix || Natural Frequency and Mode shape || Mesh Sensitivity || Open source software Hi Everyone, This video explains how to perform a modal analysis of circular shell using open source finite element analysis software . The analysis is essentially 2D. Circular shell with clamped edge configuration is considered. Uniform 2D structured mesh is used for this study. structured Quadrilateral elements were used for better performance. The results are compared with the theoretically available solutions and also the effect of mesh refinement was also studied. Three different mesh grades are used and it was observed the finer meshing yields better results.
