This is the first application of FTIR-RM and SEM/SDD-EDS mapping, qBSE imaging and nanoindentation to analyze the composition, microstructure, MD and mechanical strength of DM deposits, and the largest integrated multi-methods, multi specimens study.
The specific essential work of fracture (EWF) and the multi-specimen J-integral methods were used to evaluate fracture toughness.
The method used in this study is the compliance calibration method which employs a multi-specimen compliance calibration procedure.
Such innovative approach is compared to established methods: (i) single specimen methods, based on the determination of the energy release rate, for the calculation of fracture toughness; (ii) a multi-specimen methodology for the calibration of the geometry factor.
One of the simplest to perform is the multi-specimen low-blow or reduced velocity test and this has been selected as a basis for the ESIS TC4 procedure.
The analysis is extended to a so-called multi-fibers composite specimen, also called Statistical Elementary Volume SEVV), made of several fibers embedded in the matrix.
The results showed that the neutralizing rate of specimen in multi-gases chambers was higher by 9.6 12% than that of in corresponding single carbonation chamber.
Expeditions conducted between 1990 and 2005 explored segments of the GAR, EPR and PAR to obtain specimens for multi-species phylogeographic studies reviewed in [ 22].
The reduced scale substructural specimen was cyclically tested using the Multi-Axial Testing System (MATS) at the National Center for Research on Earthquake Engineering (NCREE).
For low temperature testing, the specimens were submerged in methanol in a Kinetics Multi Cool MC480A1 chiller for a minimum of 5 min.
Multi-wall carbon nanotubes (CNTs) were added to the CFRP composite specimen and aligned in the transverse direction by means of a magnetic field.
