“…One of such techniques is the small punch (SP) testing proposed by Manahan et al [4]. It appeared that the yield stress, strain hardening, and ultimate tensile strength estimated from the small punch test and those mechanical properties determined from the uniaxial tensile test show the reasonable correlations [5].…”

Abstract. The critical monotonic strain of Ni-W and MoS2(Ti,W) coatings on steel substrates was studied. The idea of axisymmetric bending test (called here as coin bending test) limited to monitoring of the coating failure was used. Experiments revealed mechanism of the coating failure, as cracking initiated from coating surface defects and/or substrate was demonstrated using indentation technique. By pushing the center of the uncoated side of a circular plate, the axisymmetric stress state was generated in the coating. The stress components varied gradually from the greatest value in the center to the smallest value at the edge of the specimen. The changes of the sample surface as a result of loading were monitored step by step via optical microscopy.

“…The use of small punch testing for the determination of the ductile-brittle transition temperature (DBTT) in steels of reactor vessel has been a reliable technique [55]. The fracture energy is determined from the integrated area under a load-displacement curve up to the maximum load.…”

“…1). Research and investigation in the SPT were focused on the evaluation of material properties, including the elastic modulus, yield strength and tensile strength [3][4][5], ductile-brittle transition [6], fracture properties [7][8][9][10], etc. The significant interest shown by researchers in this testing procedure motivated the development of a CEN Code of Practice for the application and use of the small punch test method for metallic materials [11].…”

The Small Punch Test (SPT) is a miniaturized test to characterize the mechanical properties of the materials. The load-displacement curve obtained by this test does not directly provide the material parameters, and linear correlations between data obtained from SPT curve and each mechanical property are necessary. The main difficulty of these correlation methods is the high level of scattering showed when analyzing a wide set of materials in the same study.In this paper, a finite element analysis focused on steel alloys was performed to understand the specimen behavior in the early stages of the SPT. Present methods to correlate the material yield strength with the data obtained from the SPT curve were also analyzed via this FEM study to discover the meaning of the current correlation scattering for this mechanical property. This numerical research also proved the accuracy of the proposed correlation method for the yield strength via the SPT. The maximum slope of zone I (Slope ini ) of the SPT curve showed an accurate correlation with this mechanical property.Focusing on steel alloys, experimental tensile tests and SPT's were performed to validate the numerical analysis and to demonstrate the suitability of the proposed Slope ini versus yield strength correlation method.
