Special attention should be paid to the strength against crack initiation at a free-edge (i.e. intersection point of the interface and a free-surface) as a severe stress concentration occurs depending on the edge shape and the elastic properties of the materials [1].
Recent advancements in micro-mechanical tools that can be combined with various microscopes (SEM, TEM, AFM) have enabled one to implement quantitatively reliable minute experiments [2-4].
The effect of free-edge shape on the properties of crack initiation strength is then carefully compared with the previous results [5].
In a Type B specimen, the near-edge sy shows rectilinear distribution represented approximately by sij = Kij/rl, where l is the singularity index and Kij the stress intensity factor.
On the other hand, the crack initiation in Type A specimens is affected by factors other than the free-edge.

Introduction Poly(phenylene sulfide) (PPS) is an engineering thermoplastic polymer, which has started to gather several industries’ attention due to its thermal stability, maintaining high mechanical properties at temperatures up to the order of 200 [ºC].
