The accumulative roll bonding process is one of the most prominent severe plastic deformation processes for obtaining sheet materials with ultra-fine-grained microstructures and high strength. The properties of such sheets differ significantly from those of conventionally rolled sheets. It is hence desirable to have a simulation framework that can accurately predict the material properties, including the evolving texture and anisotropy during processing.

Hello everyone,

I need to compute the second derivatives of displacement field in ABAQUS, in the integration point of quadratic elements if it is possible. I thought about using USDFLD subrutine, but I am stuck with getting the Jacobian matrix that couples the isoparametric space with the physical space in ABAQUS. GETVRM is what everyone suggests to get variables from abaqus, however I did not find the definitions of JMAC, JMATYP... so I do not know what I can get from that subrutine exactly.

Finger motion capturing systems have a wide variety of applications such as telerobotics, rehabilitation, and avatar control. While commercial devices are too costly, studies on such systems are either impractical to use or have speed limitations. This paper proposes a practical version of the glovebased finger motion capturing system.

Hello everyone,

I have to use an hysteretic friction model. I am trying to code this in Abaqus by using the FRIC subroutine. The language is Fortran 77.

I am testing my code on a very simple model : two plates sliding on eachother. I apply a 1 cycle sinus displacement at the end of one plate and a apply some boundaries at the other side.
