Molecular dynamics modeling of NiTi superelasticity in presence of nanoprecipitates

Submitted by Piyas Chowdhury on

The presence of nano-sized coherent precipitates is well known to have crucial impact on the mechanical behaviors of a broad class of shape memory alloys. The local stress gradient at the matrix-precipitate interface is predicted as induced by inter-lattice atomic disregistry. Due to the presence of the local disturbance fields, the preference for activating different martensitic variants, given the uni-directionality thereof, is influenced substantially.

How to apply a prestressing force to strands in abaqus?

Submitted by Dina Zakaria on

i modeled a reinforced concrete beam with a t cross-section and after loading it till 80% of its failure load, i repaired it by using post-tensioned concrete jacket.

i have two questions:

1-how to apply the prestressing force to the strands ?

2-i made interaction between surfaces of the main beam and the jacket, this interaction is tangantial and normal only, is it right or i must make cohessive also ?

 

Single Element Test(boundary conditions)

Submitted by setareh on

Dear All,

 

I want to do some single element tests for a plane stress quadratic element with bi-linear shape functions(like the plane 42 element in ANSYS).

 

What I am not sure about is what boundary conditions should be applied to the single element in this case. I also want to apply a prescribed displacement as the loading. (I would like to first try to do these single element simulations in Ansys and then with my own developed codes, hopefully the results will conform, as sort of a basic validation of my own developed code)
