cST - Ballistic event modeling

Joint Design Module for Ballistic Impact

Variant Analysis

User can vary following parameters and observe effect on impact energies, static equivalent forces, bolt stress and FOS:

• Plate size
• Plate Thickness
• Plate Modulus
• Plate Poisson's Ratio
• Plate
• Bolt Strength
• Support Spring constant
• Bolt Diameter
• No. of bolts
• Mass of Projectile
• Diameter of Projectile
• Damage angle
• Localized Shear damage                                          Click on the image for a bigger picture

Symmetric Sandwich Beam Analysis

• Analytical model developed to predict structural compliance of sandwich beams consisting of stiff outer adherends joined by a flexible middle layer*
• Model Inputs
  • Beam and rubber stiffness.
  • Beam dimensions, beam overhang
• Model Outputs
  • Beam compliance (Erub ? 0)
  • Beam compliance (Erub = 0)
  • Beam compliance with overhang and limiting compliance for overhang.
  • Corresponding beam stiffnesses for all above cases.
  • Variant analysis of all inputs.
