Dear all,
Today our colleague Zhiwei Qian defended his PhD thesis titled: Multiscale modeling of fracture processes in cementitious material. We would like to congratulate Dr Qian on achieving this. The full thesis is available for download at: http://repository.tudelft.nl/view/ir/uuid:734b276c-283a-4f7a-8db2-a1844…

Hello every body
is there any modoule in the abaqus for modeling continuum damage mechanics under creep condition?
Hellow
I am a graduate student on mechanic and I am working on the vibration
of FGM plate.
I try to model the FGM plate with Abaqus, so I need to use the UMAT
Subroutine
I don’t have big knowledge about Subroutine under Abaqus
Especially FGM materials
I’ll be thankful if some people give some guide lines about this problem.

Nanoscale fracture of graphene under coupled in-plane opening and shear
mechanical loading is investigated by extensive molecular dynamics
simulations. Under opening-dominant loading, zigzag edge cracks grow
self-similarly. Otherwise, complex stresses concentrated around
crack-tip can manipulate the direction of crack initiation changing by
30° (or multiples of 30°). Toughness determined by obtained critical
stress intensity factors 2.63–3.38 nN Å−3/2
demonstrates that graphene is intrinsically brittle opposite to its
exceptional high strength at room temperature. Torn zigzag edges are
more energetically and kinetically favorable. Cracking of graphene has
The dielectric constant is an essential electrical parameter to the
achievable voltage-induced deformation of the dielectric
elastomer. This paper primarily focuses on the temperature
dependence of the dielectric constant (within the range of 173 K
to 373 K) for the most widely used acrylic dielectric
elastomer (VHB 4910). First the dielectric constant was investigated
experimentally with the broadband dielectric spectrometer
(BDS). Results showed that the dielectric constant first increased
with temperature up to a peak value and then dropped to a
relative small value. Then by analyzing the fitted curves, the Cole–Cole
dispersion equation was found better to characterize the
rising process before the peak values than the Debye dispersion
In this paper, a correlation between simulation and a full crash test is presented. In order to achieve good agreement in the correlation, several Abaqus analysis techniques are evaluated.
The approach to modeling soil is validated by comparing predicted traction of a trolling rigid wheel to measured traction test date available in the literature. Comparison of the measured and predicted traction force shows that this approach is reasonable for predictin traction in soil.
This paper presents an automated approach to extract strains of aircraft structural models from widely used CAD and FE environments. The developed approach has been implemented as an integrated tool in widely used CATIA V5 and Abaqus environment. The integrated tool is a quick inexpensive and effecive technique for predicting structural strains.
