Hallo Jongkim, you can use the output variable nodal force NF. cheers Koe

If you use an elastic, plasticmaterial, you can use the Flag variable AC YIELD. Since it's a flag you can set the number of colors to two an use a quiltplot in the contour options.

As far as I know, you may use a maximum of 4values for the "*amplitude" card. You'll find other possibilities in this thread http://www.eng-tips.com/viewthread.cfm?qid=160575&page=3 good luck

Do you have only 0,0 and 1,-5 or do you also use some other values in between?

hallo, you can define a maximum of 4values in the amplitude card. I guess you have more than four xy-couples. cheers

hallo, you can use the variable NFORC of the field output request. cheers koe

Hello, take a look at Introduction to Compitational Plasticity from Fionn Dunne/Nik Petrinic Oxford cheers koe

hello newuser2006, the surface normal must show in the direction of the contact partner. If you're modelling in CAE you'll be able to chose the right surface of the rigid body during the surface definition. You can also import the input file in CAE and control the normals of the rigid body...

hello bakan, try it with this link www.polymerfem.com/modules.php?name=News&new_topic=13 good luck

Hello Chris, have you checked the normal of the die surfaces? this is usualy the reason for moving through rigid bodies.

try it with the chapter 5 of the abaqus example problem manuals from. by

Hello, for load cases just take a look at the chapter 6.1.3 of the abaqus analysis user's manual. for the hourglass problem, you could use another type of element or try it with the key "*hourglass stiffness" which is in your case a suboption of the key "*solid section" by

Hello, have you already defined a step in your session? if not define a step and put the load afterwards. cheers

hello, try it with the following link http://www.engin.brown.edu/courses/en175/notes_frame.htm cheers

hallo alan, i'm not sure whether you can import the abaqus module without the session object. this could be the reason for the message. cheers

there is the possibility to write a user subroutine, you can connect a spring(high stiffness) to the refnode of the rigid cone and control the force in the 2nd step. happy easter

do you want to avoid the penetration or control it? koetue

are you modelling with abaqus, if so, use the hcrit parameter in the contact pair definition or look in the manual for the card *contact interference

hi, you can enter the data from the stress-strain-curve, so that you don't have to obtain the mooney constants. you have to use the card *uniaxial test data

you find in the abaqus answers, answer id 1488. Use the link "my abaqus" in www.abaqus.com
