Adding external vibration to a dynamic analysis

Submitted by Tsinuel on
Choose a channel featured in the header of iMechanica

I am trying to simulate an experiment in which a steel plate is excited using sound vibration to measure its natural frequencies and vibration patterns. Even if modal frequency analysis of the test gave results, it was not satisfactory. Therefore, the external vibration with a controlled frequency is required to be included in the FEA model. FYI, gravity load will also be considered.

I would appreciate any help, specially related to ABAQUS. If there is no way of doing this in ABAQUS, suggestion of any other FEA software would be fine.

Thanks in advance.

Dear all,

Hi,

Any help on linking Abaqus 2016 with Intel Parallel Studio composer 2016 and Visual Studio 2015 would be appreciate.

(Note:I can't use older version of compiler as their producers (Microsoft & Intel) will not support liscence for older versions any more.)

Simulation of crack growth in Ni-based single crystals

Submitted by S. Beretta on

In a cooperative research between PoliMi and UIUC we have analyzed the crack growth in Ni-based single crystals:

 Crack growth experiments analyzed with DIC had shown relatively low closure levels respect to polycrystals. Crystal plasticity simulations with WARP3D have been able to simulate closure levels consistent with the experimental ones.

Calculation of Elastic Modulus of Graphene in LAMMPS

Submitted by almuhib on

Hello everyone, I want to calculate elastic constants (C11, C22, C12, and C66) for a single layer graphene sheet by MD simulation in LAMMPS. I am using the following equation:

 

 E = (C11*C22-C12*C21)/C22 and poisson ratio = C12/C22 from this paper:

Adsorption and Conformational Evolution of Alpha-Helical BSA Segments on Graphene: A Molecular Dynamics Study

Submitted by Jingjie Yeo on

http://dx.doi.org/10.1142/S1758825116500216 Molecular dynamics (MD) simulations are performed to investigate the adsorption mechanics and conformational dynamics of single and multiple bovine serum albumin (BSA) peptide segments on single-layer graphene through analysis of parameters such as the root-mean-square displacements, number of hydrogen bonds, helical content, inter- action energies, and motions of mass center of the peptides.
