Abaqus Tutorial Guide - How to Perform Static Analysis in Abaqus
This tutorial shows you basic of performing Linear static analysis.In this case i have considered Rectangular Cantilever block subjected to point load.so before going to the tutorial we must understand what is static load? and why we perform static analysis.
Static load
static loads are the loads which are gradually applied to the part and its magnitude and direction does not change with respect time.To check the behaviour of mechanical component under the action of static load we perform static analysis.
Create Part:
For performing static analysis i have considered a rectangular block of size 25*10mm with length 100 mm For creating the part in abaqus select 3D deformable with SOLID EXTRUSION as modeling shape.Select approximate size of the modeling space as 200 if your model dimension within this range.If your part dimension more than 500 or 700mm,then put 1000 as a approximation size of your modeling space.
Applying material properties:
After creating a part we have to apply the material properties for the select CREATE MATERIAL option.Put the name of material you are applying,the go to MECHANICAL-ELASTICITY-ELASTIC.For this case i have considered steel with youngs modulus value E=210Gpa and poisons ratio u=0.3.Put the value of youngs modulus as 210e3 N/mm2.
Assigning the material
After creating material library we have to assign those materials to a part.for that we have to choose CREATE SECTION-SOLID-HOMOGENOUS-SELECT STEEL material.Then choose ASSIGN SECTION option-SELECT PART-then OK.
Assemblying the part
After Assigning material properties ,select assembly module in that select CREATE INSTANCE-CHOOSE DEPENDENT PART-OK.
Choose Analysis type:
to apply analysis type go to step module-CREATE STEP OPTION-SELECT PROCEDURE TYPE AS GENERAL-STATIC GENERAL-OK.We are performing linear static analysis here for that we have to choose default option.
Creating mesh
meshing is the most important step in any analysis for getting accurate solution.For this select OBJECT-PART-SELECT SEED PART-PUT 1 AS GLOBAL SEED SIZE-OK.go to ASSIGN MESH CONTROL and select HEX structured element type and THEN MESH THE PART.
Apply loads and Boundary condition:
to apply loads and boundary conditions go to LOAD MODULE-CREATE BOUNDARY CONDITION-CHOOSE STEP AS INITIAL-SELECT CATEGORY AS MECHANICAL-SYMMETRY/ASSYMETRY/ENCASTRE-CONTINUE-select bottom region and select-ENCASTRE option so as to fix all degrees of freedom.
for apply point load we have to create a node set for the go to TOOLS-SET-CREATE-NODE-SELECT-SINGLE POINT in the meshing region at the front of the part.
Submit the Job:
To submit the job go to JOB-CREATE JOB-CONTINUE-OK.then in the tree file,right click on the job-1 and submit the job.After completing job submission right click on the job-1 and select RESULT option.
