Using Abaqus, how can I get Cohesive behavior, damage initiation and damage evolution parameters?

I am modelling RC beams reinforced with FRP ( GFRP,CFRP,BFRP) rebars, I have found that the best definition of interaction is, to use Cohesive behavior (it is better than Cohesive element due to...

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...
