FE PART Results
The FE PART results can be viewed in the Adams PostProcessor. By default, Adams solver generates the results set at each output time step which includes the following entities (for each node):
The generalized coordinates (global position and Euler angles) : X, Y, Z, Psi, Theta, Phi
The generalized velocities (global translational and angular velocities) : Vx, Vy, Vz, Wx, Wy, Wz
The generalized accelerations (global translational and angular acc.) : Accx, Accy, Accz, WDx, WDy, WDz
The elastic/internal forces (in local frame) : Fx, Fy, Fz
The elastic/internal torques (in local frame) : Tx, Ty, Tz
Using these results, the beam stresses and strains are computed.
Recovery of strains and stresses in beams
From the input file, we have the material properties matrix C and the geometric properties of the cross section A, Iyy, Izz and Iyz at each node, where
1. If the material is orthotropic, c1 = Ex , c4 = Gxy, c6 = Gxz, and c2 = c3 = c5 = 0, in which Ex is the Young's modulus in the normal direction of the cross section; Gxy and Gxz are the shear moduli of the cross section.
2. If the material is isotropic, c1 = E, c4 = c6 = 
, and c2 = c3 = c5 = 0, in which E is the Young's modulus, and v is the Poisson's ratio.

1. From the FE_PART results, we know the force F and torque T of each node in the local frame, and they are calculated using the following formulas
