Just for explanation purpose I have created myself, if it’s wrong please correct me on this.

Good morning every once. Presently I am working on Cv calculation of Valves with different shape of valve trim, if I change shape of stem trims Cv valve also changing. For example in Quick opening amount of fluid discharge between seat and trim are more compare to Equal opening, please refer...

thanks for your reply. I learn this topic by myself, if you have any training courses please let me know.

Hi can you please clarify my query, I can’t able to view your attachment due to login process.

Hi can you help me how to attend this course, meantime could you give me solution on my previous post. It’s urgent.

Hi Everyone Can anybody guide me how to calculate or find ΔSn,k (primary plus secondary equivalent stress range) for Fatigue assessment on elastic method in ASME 8 div 2. Thanks in advance Senthil ramajayam

Hi Idan thanks for your comments. Equation 5.7(Ɛpeq+Ɛcf<ƐL) Where Ɛpeq =Total equivalent plastic strain (obtain from FEA software) Ɛcf = Forming strain(assumed Zero) ƐL = Equivalent plastic strain (obtain from FEA software) Example: Ɛpeq = 0.037092,Ɛcf =0 & ƐL =0.038658...

Hi Everyone Can anyone guide me how to calculate how to calculate local strain limit Ɛpeq in equation 5.7 in Elastic plastic local strain limit in ASME VIII div 2. Regards Senthil ramajayam

Radius value included in the calculation. What will be solution?

i have attached https://files.engineering.com/getfile.aspx?folder=fc8f115a-a350-4d4c-9819-405a17f1bddb&file=drop_height.png

what will be the solution ?

h 500 mm.

Hi everyove I know the energy value = 5 kJ. Using potential energy equation (PE=mgh). I know the object is hitting 500 mm radius (5000=m*9.81*.5) that gives mass value = 1019 kg. Can we use this mass value in kinematic equation to find velocity (KE= 0.5mv2).I assume (KE=PE),therefore my velocity...

Hi thanks for your reply. Solid object hitting the structure. So for I didn’t get actual mass of the object, customer gave only joule. He’s there any way i can to impact with joule value

Good evening to everyone, I want to do impact analysis in ansys workbench, I got input as energy (5KJ) that will be impact in my object. I can’t able to apply as energy, any Idea like how to feed the inputs. I don’t have mass information I have only energy value, please let me know anybody know...

Thanks to all for your guidance and support

Thanks for your reply. From ASME VIII-2 Equation 3.F-1, 3.F-2 & 3.F-3 will give you only one parameter as N. To construct the S N curve we need coordinate for each points(A , B & C) as shown in Figure as example (Refer the attachments).IF I want create Point A I need X value and Y value, similar...

Good Evening To ALL Can any one please guide me how to create Fatigue Curve with help of ASME VIII Div 2. Thanks & Regards Senthil
