HI ALL
i am trying to simulate in ANSYS the Tension Strength Test (TST).The TST has been already done. i got the values(grapf stress-strain).
Now im traing to create the simulation of the TST in ANSYS. I got all the materials values:
fiber E=73GPa, V(volume)fiber=0.32 Poisson=0.25
matrix e=3Gpa Poisson=0.316
number of layers 14 (in ansys i use 29 layers, first and last is half height of matrix, plus another 13 of matrix in full heihgt and 14 of fibers)
i got the dimension of the sample (whole and the middle section).I'm modeling only the middle section.
i'm using the element SOLID46.
but the solution is different as a TST.
test value for the composite is around 16GPa
but in Ansys it is only 3GPa
any tips where i make the mistake?
thanks for all answers
