Looking for a post doc position related to my PhD work
Hello dear all,
Looking for a post doc position related to my PhD work "Mathematical Study for Multiple Cracks Weakening a Piezoelectric Plate"
Some of my publications are listed below:
1. R. R. Bhargava, and Kamlesh Jangid. ‘A mathematical
strip-saturation model for piezoelectric plate weakened by two collinear equal
cracks’, Mathematics and

Source for Mooney-Rivlin coeffcients for silicon rubber
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,

Isotropic hardening law
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 R∞ is 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
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
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?
Beam to beam elements connectivity
Hello All,
Currently, I am trying to model a layered beam one on top of other. I started with 3 layers with leaving a small gap (0.01 mm) in between. I am interested in connecting the nodes of top layer (one line representing a beam) to the adjacent beam having same number of nodes through beam elements. To be more clear, merging nodes with same element type connectivity (beam to beam).
ANSYS LINEAR EULER BUCKLING ..simple verification needed
1) anaylitical model:
Vertical Cylindrical beam under axial compression load
Height: 26.5mm, Radius: 1.25mm, E: 200000, Load factor k: 2,
Pcritical: 1,347N, Displacement: 0.0364mm
2) Beam188 model worked fine with results similar to
analytical one. (txt file attached)
3) Solid186 mold under predicts by a factor of 4 (txt file
attached)
why does the solid 186 element give different results?
Thanks
