The position is still open for apply.



You will perform research and development work using active/passive vibration control measures to reduce vibration of typical offshore structures. You will also develop new

numerical models, new control algorithm, and optimize the locations of actuator/sensors.

Curve Fitting for Viscoplastic (Anand) Model in ANSYS

Submitted by SaiSudharsanan on

Hello everyone, 

            I would like to know if it is possible to use TBFT option in ANSYS to curve-fit Anand's model parameters using experimental force-displacement data.

     I am aware that the ANSYS manual  has description for hyperelastic and even chaboche model, but is there an established procedure to obtain Anand model parameters using experimental curve fitting ? 

 

Thank you.

Hello everyone,

I've proposed a new Stack Exchange site called "Theoretical and Applied Mechanics" for people intersted in mechaics related issues.  The current link is  http://area51.stackexchange.com/proposals/67726/theoretical-and-applied-mechanics?referrer=73mdEQ3M_DdhwHImwznaBQ2

For the proposal to be accepted to go to the next stage the site will need the  following:

Sensitivity Analysis with Abaqus

Submitted by Nan Hu on

Hi, all

I'm working on a structural optimization problem invovled with running numiercal analysis with Abaqus. Therefore, it is impossible for us to use the direct differentiation method to calculate the sensitivity of design variable. But I guess there should a way to get sensitivity analysis done numerically with Abaqus. Anyone know such information or give me a short instruction on that, I would highly appreciate! 

Best Regards,

Nan 

HELP!

 Hi my friends!

I hope everythin's ok! 

As I previously said I'm doing some researches about fully developed turbulent flow inside an annuli.Now I've faced some problems. Does anyone know how can I calculate Darcy friction factor for a fully developed turbulent regime inside an annuli not using colebrook equations and moody diagram? is there any other way?

I'd be really thankful if anyone could help me .

Measurement of the Bauschinger Behavior of Sheet Metals by Three-point Bending Springback Test with Pre-strained Strips

Submitted by Shunlai.Zang on

In numerical simulation of sheet metal
forming process, the cyclic mechanical behavior of metallic sheet is
required to calibrate the material parameters of the combined
isotropic-kinematic hardening model. Therefore the development of
experimental device and method is an important work in order to
measure the cyclic mechanical behavior of metallic sheet. There are
several experimental devices which can measure this cyclic mechanical
behavior of sheet metal mainly to measure the Bauschinger behavior.
Often, these experiments can be classified into three main
categories: (i) in-plane tension-compression test; (ii) in-plane
cyclic simple shear test; (iii) bending-reverse bending test.

In this paper, a novel approach is
