Cutting iron foam samples

Hi, I have a sheet of open cell pure iron foam (porosity> 90% , thickness around 2.5 mm), and I would like to prepare 1 cm x 1 cm samples for subsequent compression tests. My foam is ductile and also it can be easily squeezed or bended with hand. I was wondering if I use a big rotatory saw (Bosch 4310, picture attached) to cut long rectangular strips (cuboids) of the foam (20 cm x 1 cm), could it significantly change the mechanical properties of the whole foam sheet, or it would change the mechanical properties of the cutting surface only.

Setting Simple Compression Test In VUMAT

Hi, i am trying to test a bulk metallc glass VUMAT with a simple compression test simulation. But since VUMAT is a Abaqus Explicit subroutine, that means I must set my compression simulation with setting of Abaqus Explicit right? So far I only have the experience in conducting compression test simualtion using ABAQUS Standard setting like static general step and surface-to-surface contact (standard). I don't know how to set up a simple compression test simulation with Abaqus Explicit settings, can anyone help me please?

Thanks and regards.
