Determination of instability of a DP 980 steel sheet under different stress states based on experiment and theoretical models

MATEC Web of Conferences, 2016
It is generally accepted that the formability of sheet metal is limited by the onset of instability which can be described by forming limit diagram (FLD) in ε1-ε2 space.

Difference of Fatigue Strength of Cruciform Welded Joints due to Specimen Configuration

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 2007
Fatigue strength obtained from cruciform welded joint specimens may be different from that of actual joints such as welded connections of lateral girder flange to main girder web or vertical stiffener to main girder flange, because main girder web is mush wider than lateral girder flange or vertical stiffener is narrower than main girder flange.

A Thermo-Mechanical Coupled Gradient Damage Model for Heterogeneous Rocks Based on the Weibull Distribution

Energies
This study develops a thermo-mechanical damage (TMD) model for predicting damage evolution in heterogeneous rock materials after heat treatment. The TMD model employs a Weibull distribution to characterize the spatial heterogeneity of the mechanical ...
