Large deformation analysis of a rubber sheet with holes.
You can use a large displacement solution.
Quire the characterisation of the deformation behaviour of a perforated sheet containing a large number of holes.
25 mm until the onset of damage.
Deformation behavior of rubber blocks and empirical relation was derived based on the assumption that the deformed cylinder has a parabolic profile under small strains.
As shown in fig.
For example a square can be deformed into a circle without breaking it but a figure 8 cannot.
But on a rubber sheet that is deformed by a small amount this relation turns out to be reversed t 3 is proportional to r 2.
The tensile displacement is applied on the top boundary in the vertical direction in increments of 0.
Rubber sheets with double edge notches.
Topology studies properties of spaces that are invariant under any continuous deformation.
The vertical stiffness and deformation theories of rubber isolators in compression and compression shear states are systemically researched in the paper a series of basic concepts such as origin.
In this study a yield criterion is discussed for the perforated sheet with uniform circular holes by employing an equivalent continuum approach which is then applied to examine the plastic deformation of the perforated sheet with non uniform circular holes.
Its fidelity for predicting large deformation is established by comparison with those of finite element analysis of a rubber sheet with a hole under stretch.
The large displacement solution is required when the acquired deformation alters the stiffness the ability of the structure to resist loads significantly.
Patenadue et al 2005 evaluated the response of elastomeric blocks under large compression strains and quantitatively measured the nonlinear behavior of rubber compounds under.
Hence a square is topologically equivalent to a circle.
This takes more time and resources than the small displacement solution but gives more accurate results.
10 the rubber sheets have two edge notches of length of a 12 16 20 24 28 mm and the notch radius is 1 mm the boundary conditions are the same as those of previous configuration with a hole.
It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken.
