hello;
tank you very much . but about racheting no ! it is new to me , i read all of the sec.5 elastic . elastoplastic and other approaches. i think i got it. but about the exact concept of racheting i am not sure.
hello ;
thank you very much Dear TGS4 ;
first , yes , i have actually read it , 5.A.4.1.2.b.1 : "stress linearization procedure" .
this is what abaqus does for stress linearization : for example membrane stress is calculated as the integrration of stress along the thickness ( abaqus chooses...
thank you all ;
as what I have known about what the software does is as follows :
the software asks two points as the start and endpoint of the SCL line , normally I choose one of the points at the node inside vessel (maximum stress) and the other one outside in a way that if the points are...
also here is the membrane plus bending and membrane diagram.http://files.engineering.com/getfile.aspx?folder=e59fcfa5-9eb7-4e33-9215-0d34f03c92f7&file=memb_along_path1.jpg
hello prex ;
thank you very much for your valuable answers , i have uploaded the result of total stress as mises and the membrane plus bending also , i have not used thermal analysis , i have evaluated the effect of temperature on young modulus and i have no heat source in the model.
also i...
hello friends;
i need to know is it possible that membrane plus bending in a region be higher than total stress in that region ? if so , what causes this happen ? and what should we name it ?
hello;
thank you TGS4 , i have read that annex , it is just the procedure that the software does it . i mean i have extracted membrane and mem plus bending and my problem is that the maximum value of membrane plus bending is higher than the total von-mises stress. i need to know why and how...
hello friends
i am doing an stress linearization in a perforated region of a connection of shell to tubesheet.
i have read the similar threads but it did not exactly solve my problem.
i want to discuss numerically.
my problem is that the stress i see as a total von mises , )not by stress...
I want to build a water ring pump with perssure ratio of 1 to 4 (bar) I want to calculate its efficiency before building it and also its other parameters such az inlet and outlet pipe diameters with respect to its efficiency but I have not found any basic about this calculation on this pump...
