Importing strain values in XFEM

Submitted by sam_uk_2000 on

Hi,

Does anyone know how to import the strain values from simulation run in one model, into an XFEM model? I am trying to model creep seprately in one model, and wanted to import the strain values of each step in that model (10 steps, representing 100 yars), into an XFEM model to find out when the crack initiates and propagates in duration of 100 years.

Thank you very much,

Sam 

Composite crushing + CZONE application

Submitted by davidrbmelo on

Hello,


I am modelling a crushing simulation of a composite corrugated coupon using Abaqus/Explicit and CZONE Abaqus' application.

I am modeling the coupon using S4R elements and the impactor as a discrete rigid shell plate with a slow constant crushing speed or high initial velocity for quasi-static and dynamic crushing simulations respectively.

I am using Hashin damage in Abaqus/Explicit and Hashin and also Tsai-Wu on CZONE application.

Source for Mooney-Rivlin coeffcients for silicon rubber

Submitted by asiminamech on

Hi everyone,

I am trying to simulate the behavior of a silicon rubber membrane which is being compressed due to the displacement od an additional part which is bonded to it. I want to model the membrane as a Mooney-Rivlin hyperelastic model. Can therefore anyone provide me with a source giving C10 and CO1 coefficients for silicon rubber?

Any help will be appreciated,

Mina

Isotropic hardening law

Submitted by felton1990 on

Hi all,

I have come across the two relations where aim to describe the isotropic hardening of a material

Power law:

R = Kεpn R is the variation in stress from initial yield, εp is the plastic strain where K is the strenght coefficient and n is the strain hardening exponent as observed in Ramberg Osgood equations.

Exponential law:

R = R∞ [1-e(-bεp)] where Ris the saturated value of the R variation, b is the rate at which the sauration is reached.

Postdoctoral Position in Computational Damage Mechanics Available at Masdar Institute in Abu Dhabi

Submitted by Rashid K. Abu Al-Rub on

A Postdoctoral Research Fellow position in computational damage mechanics is
available immediately at Masdar Institute of Science and Technology in Abu
Dhabi in United Arab Emirates. Masdar Institute is established in collaboration
with Massachusetts Institute of Technology. The research project focuses on
using advanced computational fracture and damage mechanics for simulating the
behavior of advanced materials under different loading and environmental
conditions. The candidate is expected to have a PhD in the field of Mechanical,
Civil, or Aerospace Engineering with solid knowledge of theoretical/computational
solid mechanics; continuum damage mechanics, fracture mechanics,

wave propogation in with non local deformation

Submitted by Anonymous (not verified) on

I have a one dimensional bar with a triangular pulse given at one end for 2 microseconds. The boundary conditions are free-free.I am having two cases. One in which the deformation is local (Hooke's law) and other in which the deformation is dependent on a kernel of radius r (say 5* element length).I find that the wave speed is higher when the deformation is non-local as compared to local deformation case. Is this correct? Is there a way to verify the solution?
