(0/90)s Laminate of Graphite Fiber in Epoxy Matrix
%20abc%2004212026.JPG/:/rs=w:400,cg:true,m)
Calculated Stresses at Exact Interfacial and Free Edge Intersection
(0/90)s with continuous tensile Interlaminar Normal Stress of +390 psi
which exponentially diminishes in magnitude and turns compressive (negative and decaying) inward from the free edge (Y=1) while the transverse normal and shearing stresses both vanish at the precise intersection of the free edge and the material interface - an indication of possible delamination
(90/0)s Laminate of Graphite Fiber in Epoxy Matrix
(90/0)s with continuous compressive Interlaminar Normal Stress of -42.677 psi
which exponentially diminishes in magnitude and turns tensile (positive and decaying) inward from the free edge (Y=1) while the transverse normal and shearing stresses both vanish at the precise intersection of the free edge and the material interface - an indication of unlikely cracking-type damage.
