Experimental and numerical study of the thermo-mechanical behavior of Al bi-crystal in tension using full field measurements and micromechanical modeling

Determination of the Energy Storage Rate Distribution in the Area of Strain Localization Using Infrared and Visible Imaging

“…Conclusions a) The simple experimental method allowing a determination of the distribution of energy storage rate during a tensile deformation has been presented. Similarly as in the papers [13,[22][23][24][25][26] two following imaging techniques are involved: the IR thermography and visible light imaging. The method does not require a physical simulation of the specimen heating during the plastic deformation, what was necessary in our previous works [10,11,[15][16][17][18]21].…”

“…To reach the purpose a new simple method of determination of the energy storage rate distribution has been proposed. The method requires similar measurement techniques like in papers [22][23][24][25][26]. There are simultaneous measurements of temperature and displacement distributions on the specimen surface during a deformation process.…”

Influence of boundary conditions on bi-phased polycrystal microstructure calculation

“…The recent developments of experimental techniques of displacement and strain field measurements at the grain scale (Soppa et al, 2001;Schroeter and McDowell, 2003;Tatschl and Kolednik, 2003;El Bartali et al, 2007;Moulart et al, 2009;Efstathiou et al, 2010;Saai et al, 2010) offer an efficient tool to validate a polycrystalline microstructure calculation by comparison of the mechanical fields calculated and measured and/or of the macroscopic stressstrain curves (Hoc et al, 2003;Musienko et al, 2007;Saai et al, 2010;Héripré et al, 2007). In other respects, such experimental measurement techniques can be used to identify the parameters of crystal plasticity laws using an inverse procedure (Hoc et al, 2003;Héripré et al, 2007).…”

Determination of Local Thermophysical Properties and Heat of Transition from Thermal Fields Measurement During Drop Calorimetric Experiment

“…perature fields on the specimens surface, emissivity property is classically 19 controlled using high emissivity paint on the specimen surface. Heat sources 20 estimations based on these temperature fields were proposed in [12,13].…”

“…These estimations were used to study several mechanical coupled problems 22 such as Lüders bands and necking in steels [12,14], fatigue of materials 23 [15,16,17,18], plasticity in Al olygocrystal [19], thermomechanical behaviour 24 of NiTi Shape Memory Alloys (SMA) [13,20,21,22,23], etc.…”
