What we will cover today What is Finite Element Analysis What can we use Finite Element Analysis for Overview of how to navigate Abaqus Overview of the basic procedure for performingFinite Element Analysis Specific instructions for performing static structuralanalysis
What is the Finite Element Method?The finite element method (FEM) is a numerical technique for finding approximate solutionsto boundary value problems for partial differential equations. FEM subdivides a largeproblem into smaller, simpler, parts, called finite elements. The simple equations that modelthese finite elements are then assembled into a larger system of equations that models theentire problem. FEM then uses variational methods from the calculus of variations toapproximate a solution by minimizing an associated error function.DefinitionsElements: smaller simplerparts in with equations aresolved overNodes: corners of theelementsMesh: pattern in which yousubdivide your problem into

Detailed Procedure Part: Create the Part Property Create the Materials Create the Section Assign the Section to the Part Assembly: Create the Assembly Step: Define the Analysis Type Interaction: Define how different parts interactwithin an assembly (if there is only one part thiswill be skipped) Load Define Loads Define Boundary Conditions Mesh: Create the Mesh Job: Run the analysis Visualization: View the results
Units in AbaqusAbaqus does not have units, therefore you must useconsistent units
Other Abaqus Tips Files .CAE is a file that contains everything needed to run theanalysis .ODB is the file created while the analysis is being runand contains the results of the simulation View the part Ctrl Alt Left Button: Rotate Part Ctrl Alt Center/Scroll Button: Translate Part
