RESULTS of the 4-Layer Grid "Free-Edge" Problem:

  • Stress Gradients Through the Laminate Thickness at H/B=0.998
  • Stress Singularities: From the Interior to the "Free-Edge"

Check FEM result: lfemie_mech.out/ lfemie_therm.out/ lfemie_moist.out

Stress Gradients Through the Laminate Thickness at H/B=0.998

NOTE: For this section all stresses are near the laminate free-edge: H/B=0.998

Check stress average results, savgedge_stress_avg.out, plotted below.

  
Stress Sigma-N Through the Laminate Thickness.


  
Stress Sigma-H Through the Laminate Thickness.


  
Stress Sigma-Z Through the Laminate Thickness.


  
Shear Stress Sigma-HZ Through the Laminate Thickness.


  
Stress Sigma-NZ Through the Laminate Thickness.


  
Stress Sigma-NH Through the Laminate Thickness.

Stress Singularities: From Interior to "Free-Edge"

Check stress average results, savghb_stress_avg.out, plotted below


Normal stresses in the Z-direction.

  
Shearing stresses in the NZ-plane.

  
Shearing stresses in the HZ-plane.
