Can I use Marc to run impact simulation by considering the strain rate effect? what's the main point I need to take care? How can I input the stress-strain curves at different strain rate in the material? Thanks in advance!

Marc is an implicit solver, it is slower than an explicit solver such as Dytran to perform an impact simulation. However it can be used for this type of analysis. For strain rate dependent material, you can define a table with two independent variables (strain and strain rate).
