Units • • What units does ABAQUS use? ABAQUS has no inherent set of units. How do I set the units in ABAQUS? You cannot. • • • It is the User’s responsibility to use a consistent set of units. Choose the units for Length and Force If the analysis is time dependent then select the unit for Time. • • • Example : Length – m : Force - N : Time - Sec Structural Analysis n the units for all thr other quantities are derived from it. • • Modulus, stress – Pascals Density - N/m 3 The

Example : Cantilever - Plate
