How to extract correct outer cap frame fastener loads by a Global FEM rapresenting aircraft in the current manner:
_________
|____|____|
|____|____|
|=frame as cbeam
___
___= skin panel 1 stringer bay CQUAD
In general for frame fastener load i use cquad xy shell force extraction for left and...
Can MPC RBE2 with 6 d.o.f. be used correctly to simulate bolt in FEM instead of bar and other things.....The mpc shape i'm talking is to create from a 3d model an indipendent node at one face and all dipendent connected in an umbrella shape...the other face of the same solid the other node and...
I'm trying to simulate flanges contact in patran using gap element for 2d element. can someone help me to find another way? even connecting not allined nodes?
In general to to evaluate and predict the stress results of gauge readings i read on fem for example the stress on a reference cid along the direction of sensor on quad element taking into account the z1 or z2 face...I think that there is another way to evaluate the sensor value using for fem...
Offset vectors gives wrong results in solution sequences that compute differential stiffness (NASTRAN SOL 105 and 106) and so when temperature load is assigned at nodes (NASTRAN SOL 101 too) reaching additional non realistic bending stress.A simple test can be done assigning offset in pshell for...
Supposing to have 3 fem/quad layers and a 2 allined cbar simulating fasteners crossing them.I'm in doubt about tension element results if summing (supposing 3 layers)the 2 bar element forces is as to say having resultant tension acting force on bolt....it seems to me that single element can give...
