Question 1

In a finite element model of a nearly incompressible soft tissue, which element formulation is most appropriate to avoid volumetric locking under large deformation?

Accepted Answer

Mixed displacement-pressure formulation

Question 2

For a linear elastic isotropic tissue in small-strain finite element analysis, which pair of material constants is sufficient to define the constitutive law completely?

Accepted Answer

Young's modulus and Poisson's ratio

Question 3

In inverse finite element identification of soft tissue properties, what is typically minimized?

Accepted Answer

Difference between measured and simulated response

Question 4

A first-order fully integrated hexahedral element is used for nearly incompressible tissue and exhibits an unrealistically stiff response. The most likely numerical issue is:

Accepted Answer

Volumetric locking

Question 5

A soft tissue specimen undergoes large rotations and strains during compression. Which kinematic formulation is most suitable in the finite element model?

Accepted Answer
