The　mechanical　behaviour　of　strain-rate-dependent　materials　varies　when　they　are　exposed　to　dynamic　condi-tions　(compared　with　static　ones),　and　material　parameters　like　modulus,　strength,　and　failure　strain　may　depend　on　the　loading　rate.　Simulation　of　the　ballistic　impact　effect　on　composite　materials　may　be　strongly　dependant　on　the　suitable　calibration　of　the　strain　rate　effect　on　their　constitutive　law.　Indeed,　knowledge　of　the　strain　rate　-dependent　properties　is　of　great　interest　but　still　lacks　comprehensive　studies　(i.e.,　the　effect　on　the　mechanical　parameters,　besides　strength,　is　commonly　ignored).　In　the　present　work,　three　meso-heterogeneous　models　for　2D　woven　glass-fibre　composites　under　impact　loading　were　built　considering　strain　rate-dependent　strength,　modulus　and　failure　strain,　coupled　with　macro-homogeneous　models　with　and　without　the　strain　rate　effect　on　strength.　All　the　numerical　predictions　were　compared　with　actual　ballistic　test　results.　It　was　found　that　the　accuracy　in　residual　velocity　and　damage　morphology　predictions　can　be　improved　by　considering　the　strain　rate　effect　on　modulus　and　failure　strain.
