Hi! I'm running simulations of composite laminates under impact loading. An example of VUMAT is uniFiber.f. https://cnzhx.net/fe/2015/05/09/an-example-of-vumat-using-hashin-criteria-for-composites/ At the first step, I only conduct linear elastic analysis without any damage. The element used is...

Yes, just found this: '*PREPRINT, ECHO=YES'.

The name of 'Assembly' can be modified.

Thank you. The number of terms in each line should be more flexible. I also try putting *MPC under *Part by introducing additional nodes which interact with other parts. But the results will be different.

When I used *MPC with more than 15 nodes in the data line, the number of characters in one line will exceed 256. The node set I considered is from instances so that Abaqus will automatically add a prefix of 'Assembly_'. I tried fewer nodes one line. But it seems Abaqus will ignore the...

Yes. The result by the quadratic element should be correct. The material is homogeneous and the peak value should be constant.

Linear: T2D2; Quadratic: T2D3

I guess this may be caused by the mesh size. When I refined the mesh size for the case of linear element, the decay is smaller. Any guidelines on the mesh size for such problem?

Hi, I am simulating a bar (Abaqus implicit dynamic) which is loaded at the right end while fixed at the left end. The displacement imposed at the right end is a cosine function, which lasts for one period. The results were different when I used linear and quadratic elements. What may be the...

That's true. There is a relationship between the minimum usable time increment and the element size. Thanks.

Hello, I am running a transient heat transfer simulation with a quadratic element (DC2D8). The temperature of the left edge is fixed at 0 while the right edge increases gradually to 45. But I found the temperature of the left half is lower than 0. Is this reasonable?
