Compression test

User: "LucaC"

Hi all, I have to simulate a compression test of a structure between two rigid plates and i have some questions.
Is it worth considering plates and structures as an unique component or a better solution is to create different component, with different properties (high E module for rigid for plates)? 
 Also when the upper plate comes down, at the interface between plate and structure, structure could present a horizontally displacement, caused by deformation. How I cold simulate this type of contact?

Thank you all.

    Hi LucaC,

    unique component or a better solution is to create different component

    Separate components should be created for plate and structure, as stiffness and other properties will differ for both.

     

    To include horizontal displacement, sliding contact should be defined between plate and structure. 

     

    Thank You

    Thank you Prasannak,
    do you mean 'SLIDE' in 'INTERFACES' panel?
    And what is the difference between slave and master surface of contact?
    Is it right 'CONTACT' as card image? I have to simulate a frictionless contact.

    Thank you

    Hi,
    i just tried to use SLIDE in CONTACT panel with configuration 1 and 2 but when i run the simulation both present a compenetration of material. How I can solve this problem?

    Config. 1 Contact (blu for plate and red for the structure)
