In recent years there has been a growing interest into high performance bioinspired adhesives. This communication focuses on the adhesive behavior of a rigid cylinder that indents an elastic layer coated on a rigid substrate. With the assumption of short range adhesive interactions (JKR type) the adhesive solution is obtained very easily starting from the adhesiveless one.
In Abaqus,
g(t) = 1 - ∑(gi * (1-exp(-t/taui));
in which g and gi are dimensionless.
In LS-DYNA,
G(t) = ∑( Gi * exp(-betai * t) );
in which G and Gi are in N/m2
Based on this information, how do we transform the Prony Series terms from one code to another or vice-versa given I don't have the test data available.
It is my first blog entry to iMechanica after long period of only reading.
In this review published in Chemical Soceity Reviews, we systematically revealed the design principles for bioelectronics and discussed hydrogels' merits and potential in bioelectronics.
Abstract
I would like to share our recent work published in Physical Review Letters.

Metal additive manufacturing enables production of complex metal parts that meet mechanical property specifications without the need for costly tooling. In addition, parts can be made in small batches or even manufactured on a “one-off” basis. Computed tomography (CT) scanning can be used to identify defects such as voids or inclusions that can occur in parts created through metal additive manufacturing, but in the past there was no way to determine how these manufacturing byproducts might affect performance.

Wrinkles commonly occur in uniaxially stretched rectangular hyperelastic membranes with clamped-clamped boundaries, and can vanish upon excess stretching. Here we develop a modeling and resolution framework to solve this complex instability problem with highly geometric and material nonlinearities. We extend the nonlinear Foppl-von Karman thin plate model to finite membrane strain regime for various compressible and incompressible hyperelastic materials.
Which plate theories are used in Abaqus for composite plate modeling?
