CREATING 1D ELEMENT

OBJECTIVE:

The aim is create a 1D element with specified cross section and DOF.

PROCESS:

• Initially the hypermesh is opened and the window is displayed in the below figure
• Next process is to extract the geometry on which the work needs to be done
• The user profile on which we are working is \'opti struct\'
• Then the geometry iis exported .

PROCEDURE;

MIDSURFACE:

• The given geomtery is extracted
• For the given model The midsurface needs to be exracted.
• Then further operations needs to be carried out.
• The midsurface is exctracted sepertaely for each brackets.

MATERIAL SPECIFIACTION AND PROPERTY:

• The material needs to be specified.
• We are assining steel has the material foe the given brackets.
• THen the poperties needs to be assingned speerately by right mouse clicking and it ius renamed.

MESHING:

• Then mesh needs to be created.
• By going to 2d option and selecting automesh option mesh is being created for the midsurface.

HYPERBEAM VIEW

• Intially a rod is created under specified condition
• Then a beam ( I SECTION) is created under specified condition
• Then a bar element is created under specfied cond.

CREATING 1D ELEMENT:

• The 1D option is selected,
• Totally 3 elements need to created using difeerent links and differenet DOF.

ROD ELEMENT

• The rod element is created using the RBE 2 link .
• The rod element is created with only 3 DOF switching of the rotational DOF.
• Then the element is specified with and property.
• Then the condition is updated to the elements.

ONLY TRANSALATIONAL DOF

BEAM ELEMENT:

• The beam (I SECTION) element is created using the RBE 3 link .
• The beamelement is created with all DOF
• Then the element is specified with and property.
• Then the condition is updated to the elements.

ALL DOF

BAR ELEMENT:

• The bar element is created using the RBE 3 link .
• The rod element is created with only x and y DOF.
• Then the element is specified with and property.
• Then the condition is updated to the elements.

ONLY X AND Y

SPRING

• Springs are created using spriing command.
• It connects betwween two RBE 2 link.

MASS:

• A mass of magnitude 10 kg is created suing RBE 2 link

CONCLUSION:

The elements are cleaned up and meshed and uploaded with specific needs and requirements listed, the agenda of the challenge is to analyse the cleanup tools and to get practised with 1d element tools and to use different types of links and their specifications.
