Streamline Measurement Process with Technological Advance Tooling for Measuring Brake Disc

Submitted by sifisonxumalo on Mon, 02/21/2011 - 17:31

Any who has ideas on my reseasch project.

These are the topics are need to cover for now.

1. Wearing modes to classify the disc failure.

2. What are the latest advance technological technics avaliable to measure disc brakes more efficient, 100% accurate with scale of micro's and effective.

3. Any work that has been conducted on disc brake modes literature

4. How big is this problem brake disc failure global

Dear ALL,

I am currently want to code a little program for micromechanics analysis based on FEM. But I am not sure how to implement the periodic B.C. in it. I refer the general formulations of FEM for engineers not the tensor forms. Hope you give a detailed explanation or example. Thanks very much.

Regards,

Charson Y.S.

Could any body provide MPLG basic code to test my code for problems in linear elasticity.

Damage Detection of Bridge Using Vibration Analysis and Finite Element Method

Finite Element Method

bridge

damage detection

Dear All,

I am currently working on a small academic project of Damage Detection of Bridge Structure using Vibration Frequency and Modes analysis and Finite Element method.

My questions are:

1) Is there any systematic approach to follow this problem?

2) How should I start making its mathematical model? I am considering a truss bridge. Is it appropriate to consider linear elastic deformation of simply supported beam at first point?

3) Is there any standard reference which can help me to construct its mathematical model?

George Bugliarello, president emeritus and former chancellor of Polytechnic Institute of New York University (NYU-Poly), an acknowledged visionary who brought about significant changes in engineering and education, died after a short illness on February 18. He was trained in hydrodynamics and civil engineering. His lifelong investigation was how natural, mechanical, information and energy systems affect society.

Stress intensity factor

Submitted by kirthanlj on Fri, 02/18/2011 - 17:28

hi all,

I am facing problem in understanding stress intensity factor. How exactly i can analyse crack propagation through SIF. In books it is given that SIF characterises the crack. But in numbers how can i know whether this crack will propagate for this value of SIF. According to westergaard equation crack tip stresses will go to infinity if θ and r tends to zero for any value of crack length. Please somebody help regarding this. If iam technically wrong please correct me.

Thank you
