Analysis Of Ductile-To-Brittle Transition Temperature Of Mild Steel

, 2014
The Ductile-to-Brittle Transition Temperature (DBTT) is a phe nomenon that is widely observed in metals. Below critical temperature (DBTT),the material suddenly loss ductil ity and becomes brittle. The controlling mechanism of this transition still remains unclear despite of la rge efforts made in experimental and theoretical investigation. All ferrous

Multiscale investigation of ductile-to-brittle transition in snow

, 2023
La compréhension de l'évolution et du comportement de ce matériau est cruciale pour la prédiction des avalanches et leur interaction avec des structures, ou la modélisation de l'évolution du manteau neigeux.Formés dans les nuages, les flocons de neige s'accumulent pour former le manteau neigeux.La neige est un matériau poreux, composé d'un squelette de

The influence of sliding velocity and temperature on the ductile-to-brittle transition in asperity-level wear: A molecular dynamics study

Friction
During sliding contact, asperities may undergo either ductile smoothing or brittle fracture, producing debris. A critical junction scale, d∗, governed by material properties, dictates this transition.

Stress modeling for the upper and lower crust along the Anninghe, Xianshuihe, and Longmenshan Faults in southeastern Tibetan plateau

Frontiers in Earth Science
Earthquake occurrence depth in the crust is related to stress, temperature, and brittle–ductile transition, which is also near the transition depth of the upper to lower crust. The composition variation between the upper and lower crust causes remarkable

Application of percolation model on the brittle to ductile transition for polystyrene and polyolefin elastomer blends

eXPRESS Polymer Letters, 2007
The percolation model was applied in the study of brittle to ductile transition (BDT) of polystyrene (PS) and polyolefin elastomer (POE) blends. Based on the interparticle distance and percolation model, stress volume (Vs) can be expressed by volume ...

Optimal Design of Mises Truss with Respect to Time to Creep Rapture

Engineering Transactions, 1994
The paper deals with problem of optimal choice of slope angle for bars of Mises truss in creep conditions. Results of optimization with respect to brittle creep rupture coincide with elastic solution (45°), while for ductile creep rupture there is no ...

Study of fractography of ferritic ductile iron at different temperatures and loading conditions

Materials Research Express
This study characterizes the fractography of ferritic ductile iron under various loads, including tensile, fatigue and bending, and impact conditions. The results indicate that ductile fracture is the primary mechanism observed during tensile testing at ...
