Abstract: Certain phase-transitions take place at a given temperature in the equilibrium phase diagrams, the values of their temperatures can exactly be measured so it is an essential task to calculate these values by a high accuracy.
Introduction In the field of material science, the equilibrium phase diagram has been considered one of the oldest but most useful tool as it is essential to know the transition taken place under the influence of temperature and concentration changes in the structure of materials during the planning and development process.

In that sense, interfacial failure occurs in mode I when there is a complete separation of the materials by “opening” [26].
The Brazil nut specimen allows characterization of the interfacial/adhesive strength of two dissimilar materials with respect to the failure “mode”.

Introduction
FRP materials are widely and increasingly used in aeronautical, naval and automotive industries because of their high strength-to-weight and stiffness-to-weight ratios.
However, these materials are susceptible to various defects that can be induced during manufacture or service in the form of matrix cracking, fibre breakage and delaminations.

Its controller is a Fanuc 0M, the workpiece material is ABS, and the size is 250mm * 200mm* 40mm.
Because the material adopted in this example is plastic, a manual cutting or sawing can be easily carried out, then the edge and the surface of the part are respectively trimmed and polished.
