Week - 10 Hyperelastic Material Models

 Aim : To simulate the bird strike in aero engine Boundary conditions: Following a consistent numbering approach 100000+ for nodes, 500000+ for elements, and 1000+ for the parts. All other keywords should be numbered within 10000-19999 while following a range for each one. This guideline that the student is following…

Aim: to use *CONSTRAINED_JOINT keyword and simulate follwoing joints, 1. Spherical joint 2. Revolute Joint 3. Cylindrical joint 4. Translational joint ----------------------------------------------------------------------------------------- Given problem boundary conditions: 1. Rigidbody and deformable bodies hould be…

 Aim: To calculate Mooney Rivlin and Ogden material constants and compare both using Stress-Strain data from a Dogbone specimen tensile test with 100% strain. Hyperelastic material: Material where the strains can be recovered up to 500% strain.  Given data: _________________________________________________________________________________________…

Aim: Using the mass scaling to reduce the simulation runtime and increase the stability of the solution subject to 8% mass caling.  Objectives: To understand the effect of mass scaling on the simulation by varying DT2MS and TSSFAC Limiting the percentage of added mass to 8% and optimizing the DT2MS Comparing implicit…

Aim: Using the stress-strain data obtained from laboratory test to create the material data card and validate it by performing dogbone uniaxial tensile test.  ______________________________________________________________________________ Objectives: 1. Convert the given test data (Stress-Strain) by plot digitizer…

 Goals: To simulate the head impact under following cases. 1. Simple head impacting rigid wall 2. Headform impact with rigid wall 3. Headform impact with hood  --------------------------------------------------------------------------- Deliverables:  1. Stress-strain plot 2. Head acceleration plot 3. HIC…

Objective: Calculation of engineering stress, strain, true stres, strain and the stretch ratio for an hyperelastic material for different element formations (1,-1,2,-2) ----------------------------------------------------------------------------------------------------------------------------------------- Given problem…

Aim: Simulation of spot welded plates crashing a rigidwall. Given conditions:  1. Beam and solid elements to be used for spotwelds.  2. Steel material is to be used for spotwelds. 3. *MAT_SPOTWELD card has to be used. 4. Spotwelds have to be symmetric   Considerations: 1. Initial velocity 50 km/h 2. 5 spotwelds…
