This paper explores the specimen-dependence of the resistance (R-) curve for fracture of materials showing a pronounced R-curve effect.
In addition, a Weibull analysis shows for surface-micromachined specimens a dependence of the strength on the specimen length, rather than the surface area or volume, which implies that the sidewall geometry, dimensions and surface conditions can dominate the failure process.
Despite microstructural differences between the HP and PECS-processed specimens, the porosity dependence of the mechanical properties was a function of the total volume fraction porosity, P, independent of the details of the size and spatial distribution of pores within individual specimens.
The understanding of the dual specimen-size dependences of plastic deformation capability of BMGs is helpful for the potential and reasonable engineering applications of BMGs.
The burst strengths of the specimens were determined, and the dependence of the burst strength on the crack angle was examined.
Aim of the research was to select the best application conditions of the two products on salt-laden stone specimens, investigating as well the dependence of the protective action on the procedures adopted to apply the products.
Details of specimen preparation; full details of the dependence of the 2D band position upon strain for monolayer, bilayer, trilayer, and few-layer graphene; schematic illustration of straining of the trilayer graphene lattice leading to the loss of Bernal stacking and calculations of the energetics of formation of the dislocations and stacking faults.
The results of finite element simulations of the specimen offer an explanation for the directional dependence of fracture on the basis of the continuum crack tip fields.
This complicated response may be implicated in the dependence of the results on specimen geometry.
Quantitative metallography was conducted on heat treated and quenched specimens to acquire additional information on the dependence of the phase fractions on temperature.
This work studies the strength dependence of single-crystal metal specimens of submicrometer size on their dimensions.
