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. I would use the saw only to prepare the cuboids as the first step of the sample preparation. As the second step, I would cut the rectangular strips into 1 cm x 1 cm cubes using a small rotatory tool (Dremel) and a holding gadget. It is important for me to keep the consisteny between the properties of my samples. I would appreciate your input.

Regards,

Reza

在VUMAT设置简单的压缩试验 //m.limpotrade.com/node/10093 < div一堂课s="field field-name-body field-type-text-with-summary field-label-hidden">

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.
