Week-6 Calculate the Stretch Ratio by comparing the ELFORM (-2,-1,1,2) with Ogden_Material Model.

AIM:Create a block of 10mmx10mmx10mm dimension with 10 elements for each direction.Simulate the tensile behaviour of the block and compare the results of the simulation using ELFORM 1,2,-1,-2.

• Create the box of solid crossection in the LS prepost.
• 
• After creating the given model creating the section for the given model.
• 
• we should import the given material for the model.
• 
• we should assign the material and section model for the part in the model.
• 
• we should create the spc boundary condtion for the given model.
• Restrict in X- direction:
• 
• 
• Restrict in Y-Direction
• 
• 
• Restrcit in Z-Direction
• 
• 
• We should have to create a motion boundary for the given model.
• 
• we should create a curve in the prescribed motion in the given model.
• 
• 
• we should create the control termination,implicit auto,implicit solver,implicit solution,implicit general for the given model.
• 
• 
• 
• 
• create the ASCII file and bnary plot for the given model.
• 
• 
• 
• we should check the model checker for the given model.

• CONCLUSION:-

  By changing the element formulation normal stress changes each case as shown below.

  case 1-Element formulation is 1, normal stress is increased gradually.

  case 2-Element formulation is 2, normal stress is decreased at the end of the simulation.

  case 3-Element formulation is 3, normal stress is decreased.

  case 4-Element formulation is 4, normal stress is decreased end of the simulation.
