Bimaterial interface modelling using ABAQUS

Hii all,

How can we model a bi-material interface using abaqus. 

Aircraft Wing Dynamics

Choose a channel featured in the header of iMechanica: 


I am looking for any resource where I can get some data regarding the average force and its time variation with which the wind applies force onto an aircraft body especially the wing. To reframe the question in a better way: can anyone recommend a resource that has data about the wind velocity profile around the aircraft (especially the wings) or pressure/shear force profile on the boundary of the aircraft (especially the wings) during various phases in its flight. 



 I am trying to model a sheet of Poly Vinyl Butryl (PVB), which is a viscoelastic material in ANSYS. I have all the regular properties like elastic, shear and bulk modulus, poisson ratio, denstiy and damping factor. I also have a stress- strain curve of PVB. With all this data, is it possible for me to find the various constants in the viscoelastic models using ANSYS?



need help,abaqus Umat/Vmat for functionally garded material


iam looking for abaqus Umat/Vmat for functionally garded material, is there any one who can help me with sample or code? 

thank very much

Torsion of annular rod with longitudinal slit

Choose a channel featured in the header of iMechanica: 

I have a question regarding simple torsion of a circular shaft with a uniform cross section. Given a hollow circular shaft with inner radius R1 and outer radius R2, length L, shear modulus G, fixed-free boundary conditions and applied torque T about the central axis, the equation for the rotation angle at the end of the beam is

 phi = T*L/(J*G)

where J = pi/4*(R2^4-R1^4)

which software is use for simulate ultrasonic turning it possible in ansys?

fatigue crack growth curve

Choose a channel featured in the header of iMechanica: 

I implement a program for fatigue crack growth in the XFEM.

But I have great difficulties to find material parameters used for PARIS- or  FORMAN/METTU-equation.

Can anyone point me where this parameters could be released, for example for epoxy, polyurethane, 18CrNiMo7-6 and Aluminium.

I would very appriciate your response.

Distributed Coupling in Abaqus

Hi all,

I am trying to replicate an analysis done in Abaqus by using LS Dyna. I've an input(inp) file of the abaqus model on which the analysis has been performed.


My research field is Numerical methods in fluid dynamic. The method that we use named CDLS mesh-less method. It is based on MLS shape function and Least square equation discretization.

We decide to change our shape function from MLS to RPIM. We predict if this shape function couple with our method, we will reach better results in fluid dynamic problems. But we don't have any experience in using this kind of shape functions.

Now I am looking for a person who has experience in working with RPIM shape function for cooperation.

Dear All,

The first article of Pr. Engelmayr's Lab entitled

"Finite element analysis of an accordion-like honeycomb scaffold for cardiac tissue engineering" Aurelie Jean and George C. Engelmayr Jr.

is available in early view on the website of Journal of Biomechanics !

Alternate expressions for the near-tip in-plane mixed-mode K-field stresses and displacements

Alternate expressions for the angular variation of the K-field stresses and displacements around a sharp-crack embedded in an elastic medium subjected to an in-plane mixed-mode (mode-1 and -2) loading are presented. The expressions are derived in terms of the mode-mixity angle instead of superposing the pure-mode fields. The alternate expressions are derived using complex potentials and the Kolosov-Muskhelishvili method. The mixed-mode stress and displacement fields are presented in the crack-tip Cartesian and polar coordinates. We have obtained the crack growth angle in terms of the mixity-angle assuming the maximum hoop- and principal-stress criterions.


Thermal buckling analysis of a radially graded annular FG plate with temperature dependent properties

Dear all

I'm working on the thermal buckling analysis of a radially graded annular FG plates with temperature dependent properties.

The results show that the temperature dependent thermal buckling loads are greater than those of the temperature independent, but I have expected for vice vesa results!

Can anyone explain it ?

Modelling a spring shape memory alloy


I am a Masters student and I need to model a spring shape memory alloy in ABAQUS. I have found a UMAT file,however the file contains the geometry of a 1X1X1 cube. Does anyone have any idea of how I could copy the geometry of the spring(which i modeled in solidworks and imported to ABAQUS)into the input file of the cube,so that I could run the model in ABAQUS. I have tried this but ABAQUS is giving me errors

Or does anyone have any other idea of how I could model a Sping SMA in ABAQUS?






Temperature dependence of the thermo-mechanical properties of aluminum

I'm looking for the thermo-mechanical properties of aluminum, such as  Young modulus, thermal expansion coefficient, thermal conductivity coefficient and poisson ratio as a function of temperature :

E=E0(1+E1*T+E2*T^2+E3*T^3)  ;  T: temperature in K

Good book(s) on beam and plate theory.

Hi all ... can somebody suggest me good book(s) on plate/beam theroy? The book should start for a novice and should go till large deformation part. Step by step explanation atleast for first few chapters should be there. Thank you.
