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.

Surrogate-Based Shape Optimization of a Cruciform Specimen for Biaxial Testing of Microparticle Reinforced Epoxy Adhesives

Applied Sciences
Reliable determination of the in-plane biaxial mechanical behavior of particle-reinforced composite adhesives under multiaxial stress conditions requires cruciform specimen geometries that achieve high stress uniformity in the measurement zone.

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.

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 ...

Biaxial loading effects on large -scale cruciform specimens

, 2015
To address the influence of biaxial stress effects on fracture, experimental work has been reported in theliterature on cruciform specimens containing defects. For example, some large-scale tests were carried outfor the US Nuclear Regulatory Commission at the Oak Ridge National Laboratory in the 1990s,concluding that biaxial loading in the form of an ...
