Week 4-1D Element Creation Challenge

AIM:

       Meshing and create cross section with given dimensions.

OBJECTIVES:

•             Meshing is finite element analysis the goal is to stimulate some physical phenomena using a numerical techniques called FEM . SO IN fem ,we create a mesh which split the domain into a discrete number of elemnts for which the solution can be calculated.

•             Cross section area ----when a plane cuts a solid object an area is projected onto the plane.that the plane is perpendicular to the axis of symmetry.

PROCEDURE:

       STEP 1: GIVEN COMPONENT

         

   STEP 2: 

                    Select the both surface- then create mid surface.

       Go to geometry---midsurface--create.. 

  STEP 3:

                     Meshing the component with given size.

        Go to 2D---size and bias---size=5 unit--- mesh type is mixed--- then mesh it

       

      

      STEP 4:

                      TO CREATE RB2--- TO MAKE MULTIPLE NODES

        GO to geometry----quick edit---unwasher line----select the each part and make a rigid circle

            

     STEP 5:

               Create cross section and DOF for given elements.

             To create rigid----Rb2 ---Go to 1D ---RIGIDS--select calculate nodes---multiple nodes---by pathh---can create multiple nodes-----change element type---create rb2link. 

            In rb2 classes are also created... 

          Go to 1D--- masses---select node point---Cmass will be created. 

             

                   

       STEP 6:

             To connect the both '' a ''cross section CROD as rb2 link

                     

       STEP 7: 

            As same as bar and beam cross sections.

            

         STEP 8:        

                   To make solid cross section of each type. 

            Go to 2D hyperbeam----standard section----solidsection for CRod.. 

            

      STEP 9:

          As  Same  for Cbeam &CBar

•    For Cbeam -----select I-section with given dimension..
•   For CBar--- select cross --- with given dimension.. 
•     Then create seperate component and property for each cross section.. 
•                     

         STEP 10:

          As same for ''' d & e''' component create rigids rb2 with given mass and magnitude.. 

                   

       STEP 11:

                   For ''f'' component between any two nodes spring has to be created... 

                 Go to 1D ----  select Hspring----then select two nodes... then spring will appear.

                      

         STEP 12:

                Hence , cross section, mass and magnitude are created with given dimensions.. 

                   

          RESULT:

                    Hence, the 1D element are meshed and cross section are created with given dimensions.
