Hi all, hope you're well. I am fairly new to ABAQUS and have been trying to teach myself this software. I've been attempting to model a 3-wythe brick wall using this article as supporting literature: https://www.sciencedirect.com/science/article/pii/S0141029616314833. All the values in my ABAQUS model have been taken from this software, such as Drucker-Prager, Young's Modulus, cohesion, etc. However, every time I visualise my model, only a small part of the model is affected and thus you cannot recognise any wall pattern cracks. I am trying to recreate Wall nr. 3 from Manzouri et al's lateral resistance of URM walls experiment ( https://journals.sagepub.com/doi/abs/10.1193/1.1585916), and the wall crack patterns look as such:
mine look as such (x6 magnified brick units, to keep myself under the 1000 node limit of the learning edition, but principal stresses/deformation should still follow the same-ish pattern):
Would it be something to do with my time step/increments (i only go up to 28 increments with step time = 1)? that I am using too small of a time range or something? or any other reason? I'm not sure so any help would be greatly appreciated... I hope I do not sound silly, this software is quite confusing for a newbie.
