Entering in real industry job at the age of 29 with masters or 32 with Phd which will be better ?. Bcs now a days industry looks staff <30 am i right ?.
Hi all,
I am basically mech engineer. At present am bit confusion for choosing my permanent job. Here are my exp's. I finished my bachelor in eng 99' after that i had worked as a cnc programmer for one yr. After that i had 1.5 yrs exp as a CAD programmer in well known firm. Then next 2.5...
thanks paulliu, I have the gear models both for spur and helical tooth in patran(solver Nastran). I hope this helps me + ur tipps and links. Let me proceed and come with solns.

Thanks to all. yes we r looking the load sharing on the planets. we already developed profile correction program for constant torque. Right now lighting for variables torques. any web links for 3D elastic contact problem analysis ?.
I just want to find the load distribution along the face width with variable torque. Virtually, each mesh has uneven load distribution along the width, may very small in planetary gears. Its possible to have the even load distr. by doing profile correction on the flank. For that one has know the...
Hi all, Its necessary for my research to find KHBeta as a function of profile correction value (µm, crowning correction) and variable torque, so KHBeta-i = f(Ti,Kj), though i have some doubts what r all the actual parameters will play role in it. The aim is to find KHBeta in planetary gear of...
Hi all, i want to do miners rule analysis for gear. So that i have the following input parameters:
1. number of teeth (14)
2. Heat treat : case carburized
3. Operating torque
4. Operating speed
5. Operating time
6. Operating stress
7. Allowable stress
with those parameters, would like to know...

thanks to all, actually my ultimate aim is to correct the tooth profile to reduce the tooth root damage as a funtion of applied torque and speed. For that i have to know the parameters such as fatigue life, durability, crack initation, crack length, etc.
I have tooth root stress values which...
Thanks, At the moment we dont have license for MSC.Fatigue. is it possible to do fatigue analysis in MSC.Nastran ?. or any other FEA softwares which are able to fatigue life analysis ?.
I havent started practical test yet before that i could analysis theortically how the crack initiates in tooth root by using fracture mechanics. thanks
Hi all,
I am doing gear tooth failure analysis for that i could know the following in fracture mechanics:
1. How to find crack initiation and crack propagation ?. (i found some articles about crack propagation but still i dunno about crack initiation, i mean to find a, where it initiates...
Thanks Eric and gbor. sorry guys if i am in wrong forum. I will post my query in the mentioned forum too. my main aim is to find the partial damage of the tooth root as function of torque and speed in planetary gear. still i dont have an exact idea to do it, but before i would know all the...
