What units are used in ABAQUS?

There is no inherent set of units in ABAQUS. It is up to the user to decide on a consistent set of units and use that units. Typical sets of units :

1 2

Length - meters mmForce - Newton's Newton'sTime - second second

Mass - Kg tonne (**) Density - Kg/m3 tonne/mm3Stress - N/m2 N/mm2 (= MPs)Young's Modulus - N/m2 N/mm2 (= MPs)

** 1 tone = 1000 kilograms

This deals with the behavior of structural steel–concrete composite beams curved in plan. The finite element package ABAQUS has been used to study the nonlinear behavior and ultimate load-carrying capacity of such beams. A three-dimensional finite element model has been adopted. Shell elements have been used to simulate the behavior of concrete slab and steel girder, and rigid beam elements to simulate the behavior of shear studs. The proposed finite element model has been validated by comparing the computed values with available experimental results. An acceptable correlation has been observed between the computed and experimental results obtained for beams of realistic proportion.

Concluding:
