Dear Friends,

     I have developed a ser of 2-D finite elements for the problems of structural mechanics. These two dimensional elements are capable of accurately predicting three dimensional stress states using three diemnsional constitutive law. My doubt is: can these elements be used for the analysis of 3-D crack propagation using XFEM?.  The displacements chosen for these elements are simple.

Hi,

     Is it possible to use 2-D finite elements capable of accurately predicting all stresses (three dimensional stress state) for 3-D crack growth simulation?

Subramanian

I am writing user-defined element using ANSYS. Are any general guidelines available? Kindly help me.

Hi all,

      If an analytical model predicts accurately all stresses, including transverse normal stress across thickness, using constitutive law for the analysis of laminated composite structures, what is the use of this model and where can  I apply this model in composite structures and fracture mechanics?. Further this model is amenable to linear/nonlinear finite elements with less degrees of freedom per node (C0 and C1 finite elements are possible).

Bye

I have developed a set of simple and highly accurate two dimensional finite elements for the analysis of laminated composite structures. These elements are capable of accurately predicting three dimensional stress state (all six stresses) using constitutive law.  These elements reduce modeling effort, computational time and increase solution accuracy.

Can someone suggest me a proper source to support my research financially?

Dear friends,

     Is it possible to call nonlinear UEL and nonlinear UMAT for the same problem in ABAQUS?
