how 'PeritriaxController' control stress on boundry

Asked by 张文卿

I'm using 'PeriTriaxController" to impose stress on my model.But when I read C++ file ,I found that it get strain_rate by stress difference.How does 'strain_rate' work?Does that mean the program move every particle by their coordination and strain_rate?
particle displacement=particle coordition*strain_rate*dt.Is that right?
