  hello
  
  I am modelling a concrete cylinder that is pressured dynamically with a load that has a constant amplitude
  Smaximum is 70% of the compressive strength of the concrete and Sminimum is 5%
  
  Everytime i add sine function with a frequency of for example 8 /s it shows me a non constant amplitude in the graph when i add more steps
  
  it doesnt seem like 8 cycles per second and it doesnt have a constant amplitude
  
  Any help would be nice
  
  thank you
