Adaptive periodical representative volume element for simulating periodical postbuckling behavior
Finite element method (FEM) with fixed representative volume element (RVE) encounters some difficulties in simulating the periodical postbuckling behaviors of infinite long beam or infinite large film on soft substrate under compression, because the wavelength and pattern of buckling are not known before simulation and will change with the increase of compression strain.
SIF semi-elliptical crack in pipelines
Dear all,
I am working in my under-graduate thesis. Basically, i'm trying to calculate the SIF and J-Integral for semi-elliptical surface crack using CINT command in ANSYS APDL (all of this in a pipeline model). I have seen one paper shows SIF's distribution along the crack front like the following picture (fig. 8):
In my analysis I have obtained the following distribution (I have used a/c=0.5 with a/tc and tc/Rc equal to the fig. 8):
Microstructurally based cross-slip mechanisms and their effects on dislocation microstructure evolution in fcc crystals
Three newly identified cross-slip mechanisms from atomistic simulations of fcc crystals, namely surface, bulk and intersection cross-slip types, were hierarchically informed into discrete dislocation dynamics simulations. The influence of each cross-slip type on the evolution of the dislocation microstructure in face-centered cubic microcrystals having different crystal sizes and initial dislocation densities was investigated.

Can anybody help me in using smeared crack and cohesive zone modeling in concrete for different grades. I was actually facing problem in using the same to identify fracture parameters of concrete using ABAQUS. I will also be helpful if anyone let me know about an alternate method to find fracture parameters of concrete using ABAQUS apart from using models. Thanks in advance.......

Optical microscope for three-dimensional surface displacement and shape measurements at the microscale
We report a novel optical microscope for full-field, noncontact measurements of three-dimensional (3D) surface deformation and topography at the microscale. The microscope system is based on a seamless integration of the diffraction-assisted image correlation (DAIC) method with fluorescent microscopy. We experimentally demonstrate the microscope’s capability for 3D measurements with submicrometer spatial resolution and subpixel measurement accuracy.
