Hi Cat - What are the restraints in the model? If you are restraining the base feet the model will be much stiffer then in practice. Restrain the table or better still say a block "vice" on the table so the load loop goes from the tool to the vice which is then correct. CSA or UHPC start at 26GPa and through to 80GPa. Epoxy granite starts at 20 and can get to 40 as epoxy has poor stiffness. cheers Peter
