The BioManufacturing and Vascular Device Laboratory at the University of Pittsburgh seeks a dedicated Graduate Student Researcher, interested in developing novel manufacturing processes and realizing advanced biomedical devices (http://www.pitt.edu/~yjchun/home.html).
good morning,
im PHD student in france working in stent problems,
i want to simulate only superelastic model of nitinol in ABAQUS (
Auricchio's model)
some doc are available in th internet, but still confused
how can i idintify this material in Abaqus?
do i have to code this model and write subtoutine in fotran or it
already exists in ABAQUS ?
what is in summery the steps that i have to do??
thanks 4 giving some of ur time 4 this question
ALTNJI.
BEST REGARDS.
Good afternoon all,
I'm trying to simulate high impact loading and fragmentation of concrete for my dissertation.
Hello,
I want to do modal analysis of a structure with viscoelastic material. The viscoelastic
material has a complex youngs modulus E= E (1+i*g), where g is the loss factor. In ANSYS, modal analysis ignores all
nonlinearity, so how can I perform modal analysis with viscoelastic material?
OR
How can I perform modal analysis in ANSYS considering hysteretic damping (complex Young’s
modulus E= E (1+i*g) as input).
Cheers
HI all,
sorry my bad english,anyone could help me?
I' am a begining in abaqus, why the data in abaqus viscoelastic model are entry with shear test? and not with uniaxial test?
How introduce they for polymers materials?
thank you
Advances in molecular assembly are converging to an ultimate in atomistic precision —nanostructures built by single atoms. Recent experimental studies confirm that single chains of carbon atoms —carbyne— exist in stable polyyne structures and can be synthesized, representing the minimal possible nanowire. Here we report the mechanical properties of carbyne obtained by first-principles–based ReaxFF molecular simulation. A peak Young’s modulus of 288GPa is found with linear stiffnesses ranging from 64.6–5 N/m for lengths of 5–64 ̊A.
Hi All,
I am a PhD student working with anisotropic elasticity to model T-stress. I understand the simplicity of derivation in Stroh formalism but am lost in the Matrix algebra whereas Lekhnitskii provides complex derivation for the formulation but on first glance, it seems more user friendly for numerical modelling.
Does someone have an experience in modelling the either one formalisms with MATLAB and could he share his experience?
Thanks for the sharing of information.
