With the boundary conditions, analytical styles of stress intensity factor and stress field at modeⅠ in anisotropic composite materials near the parabolic crack tip are obtained.
In addition, analytical expressions of displacement field and stress field at modeⅡ in anisotropic composite materials near the parabolic crack tip are also deduced.

The limitation of EDM is its slow machining process with low material removal rate (MRR) when machining hard materials with complex shapes since its material removal principle is non-contact electro-discharges with minimal physical forces [4].
Materials and Methods Experiments were conducted on PMEDM process to machine titanium alloy using cop-per-tungsten material as electrode with square cross-section of 9x9 mm.
Hasçalık and Çaydaş [9] stated similar effect of conventional EDM on titanium alloy using graphite and aluminum electrode materials.
