This is done by writing and solving the equilibrium equations at the open degrees of freedom. We show, in this chapter, that instead of writing the equilibrium equations from first principles, we can instead assemble the system stiffness matrix by a relatively simple algorithmic procedure....

It could be boundary condition, also from the number of Gauss, and element stiffness matrix. To find out why do you have this behaviour, you could double check the code and the formulation. I also can suggest you to increase number of elements to see does it increase the accuracy of ...

Inclusion of COAM did not alter the microstructure of the fibrin hydrogels at the fiber level while affecting the SAP hydrogel microstructure (homogeneity), leading to fiber aggregation. The stiffness of the SAP hydrogels was sevenfold higher than the fibrin hydrogels. The viability and attachment ...
(RADA16) is available in non-GMP grade from various vendors, including 3-D Matrix and others. The same applies to other research purpose polymeric systems which are indeed less expensive to manufacture. Again, compounds destined for medical purposes are subject to strict regulatory and quality ...
However, one of the most important properties of hydrogel-based scaffolds is mimicking the physiological milieu that favorably encapsulates cells and forms a 3D extracellular matrix with high pore interconnectivity [9]. Recently, self-assembling peptide nanofibers, a hydrogel-based scaffold, have been ...

In this algorithm the stiffness matrix is assembled by groups of lines related to each node of the finite element mesh. Therefore as each processor will only assemble the lines related to a specific group of nodes, no synchronization is required to avoid that two or more processor try to ...
