THE BEHAVIOR OF AGGLOMERATES UNDER TENSILE STRAIN

Polar domains in lead titanate films under tensile strain.

Thin films of PbTiO3, a classical ferroelectric, have been grown under tensile strain on single-crystal substrates of DyScO3. The films, of only 5 nm thickness, grow fully coherent with the substrate, as evidenced by synchrotron x-ray diffraction. A mapping of the reciprocal space reveals intensity modulations (satellites) due to regularly spaced polar domains in which the polarization appears ...

Compression behavior of porous dust agglomerates

Context. The early planetesimal growth proceeds through a sequence of sticking collisions of dust agglomerates. Very uncertain is still the relative velocity regime in which growth rather than destruction can take place. The outcome of a collision depends on the bulk properties of the porous dust agglomerates. Aims. Continuum models of dust agglomerates require a set of material parameters that...

Analysis of the Thermomechanical Behavior of Coarse-grained Polycrystalline Aluminum under Tensile Conditions

The aim of this paper is to present the advantages of using Digital Image Correlation (DIC) and Infrared Thermography (IRT) to investigate the thermomechanical behavior of aluminum at the scale of its microstructure. The study combines these complementary imaging techniques: Electron Backscatter Diffraction (EBSD) to characterise the microstructure of the sample, DIC to obtain strain fields and...
