Dear Abhilash,

Simplest way to consider body load of 9g is to apply gravity (with value of 9g) and carry out static analysis. However, this may not be your actual case. Do you have any other information about the 9g load in terms of acceleration with time (single pulse or multiple repetitions) and place at which it is seen (or applied)? Is it base excitation or acting at a point on the body? What is the excitation source?
