strain is always unitless, give 0.01 for1%.

Ali Raza

Strain is a unit less parameter. but in ABAQUS while using the SI units, mm/mm in percentage should be used for strains.

Quy Thue Nguyen

unitless

Rolf-Hugo Kirkvik

Agree, give as absolute number e.g. 0.01 but make sure that the metric elasticity module E=2.1 x 10^11 N/mm^2.

Khondaker Sakil Ahmed

Abaqus is unitless. You can use any unit. However, you have to stick with same unit in everywhere. Like N and mm. No matter what unit you use but you have to be consistent and same for output.
