Mar 14, 2007 #3 PamCrash Industrial Nov 30, 2004 75 Sorry, was wrong in my previous post. Use: Length = meter Time = seconds Mass = 1E6 kilogram = 1 kt (kiloton) Derived units: Stress: 1 MPa Force: 1E6 N = 1 MegaNewton Density: 1e6 kg/mm³ = 1 kt/mm³ Upvote 0 Downvote

Mar 15, 2007 Thread starter #4 Yoman228 Marine/Ocean Mar 5, 2007 176 Please would you kindly to check this for me. Stress in MPa = N/mm^2 = MN/m^2, Hence Stress is MN/m, Then Force = MN as you stated. time = s, Gravity is MN/s^2, hence Gravity = 9.81E-6 MN/s^2 Pa = kg/ms^2, so 1 MPa = 1Mkg/ms^2 = 1 ton/ms^2 so if an structure weight 1 ton, the input in ABAQUS is 1.

Mar 15, 2007 Thread starter #5 Yoman228 Marine/Ocean Mar 5, 2007 176 oh, forgot the most important density. If a structure have 1000 kg/m^3 = 1 ton/m^3. so the ABAQUS input is 1. Could anyone kindly confirm that this is correct? Upvote 0 Downvote

Mar 15, 2007 #6 PamCrash Industrial Nov 30, 2004 75 Gravity = 9.81 m/s² Mass unit is kt. So a structure of 1 ton = 1000 kg is to input as 1e-3 Density input is kt/mm³, which is equivalent to 1e6 kg/mm³ = 1e15 kg/m³. So 1000kg/m³ is to input as 1e12 Upvote 0 Downvote
