RESULTS of the "4-Layer Ply-Crack" Problem
Stress Gradients Through the Laminate Thickness
Without a 90 Degree Ply Crack

Check FEM results:lfemi4lnc_mech.out/ lfemi4lnc_therm.out/ lfemi4lnc_moist.out
Check stress average results, savg_stress4lnc.out, plotted below.

NOTE: All stresses are far from the laminate free-edge: N=0 and H=0

  
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.
