skins in abaqus

[elahe337]

hello every one
I model my object in Abaqus, assign a skin in property modulus, and assign a module of elasticity and yield stress.
I want to know regardless of its module of elasticity and yield stress, does skin make my model more resistant to impact loading?

 

[FEA way]

Yes, check the article "Use skins and stringers for shell or beam reinforcements in Abaqus" on Simuleon’s blog which features an example of a foam block stiffened against impact with the help of skin.
