@negativevolume the only reason is to save analysis time.

As my last suggestion : You can use RCFORC data written for contact transducers (*CONTACT_FORCE_TRANSDUCER_PENALTY) to extract any contact forces. A...

first of all check the normal direction of shell parts and if inelastic response of shell part is expected set NIP to a minimum of 3 on section_shell ...

@sheida In case of structural damage due to such impact, self-contact may occur, so set the self-contact condition on the target structure or on the p...

you can use mat 024 or 03 for projectile with the following set up: contact-automatic-single surface SSID=shell plate, MSID=0 SSTYP=3 and MSTYP=...

@anuragdogra what kind of contact did you define?

Hi, check the direction of the normal of shell elements

@icebreakersours thanks a lot.

@icebreakersours Thank you for your suggestion. Please check modeling file if possible. 😟 😟

@icebreakersours this modeling is intended to validate an experimental test. The loading protocol is also selected from the same experimental work. ...

the modelling job file(k file) also attached.  Column.k

@negativevolume Thank you. I am very eager to hear your comments on the subject.
