Hello everyone, i am trying to understand a non linear simulation study. I have attached few images. My concern is, what does the time curve with x and y values under the force, show ? i have entered x=0,y=0 and added another row below and put x=4,y=4. Does that mean that i have applied force starting from 0 seconds to 4 seconds? Also, i have set the end time as 1 second. in the properties of the study. i noticed with increase in end time i set, the stress,displacement and strain also increase. i am able to set end time maximum till 4 seconds. If i set my end time as 1 second from properties, Does this mean that the force i have applied is acting on the body for 1 second? This whole test is for a car hitting a barrier,producing 75000 newton force, and i need to know whats the maximum displacement the barrier will go?

Also, if i set higher end time, after a certain value beyond its yield strength , the material will face fatigue.  Is there a way to find that value?

If any one can help please.
