The tensile displacement is applied on the top boundary in the vertical direction in increments of 0.
Large deformation analysis of a rubber sheet with holes.
It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken.
Deformation analysis of silicone rubber sheet subjected to keen wc blade indentation article in international journal of automation technology 8 5 761 772 september 2014 with 32 reads.
Quire the characterisation of the deformation behaviour of a perforated sheet containing a large number of holes.
This takes more time and resources than the small displacement solution but gives more accurate results.
Hence a square is topologically equivalent to a circle.
As shown in fig.
Rubber sheets with double edge notches.
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.
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.
You can use a large displacement solution.
Also its validity for predicting damage is demonstrated through simulations of experiments concerning progressive damage growth and final rupture in polymers undergoing large elastic.
The analysis of the stress and strain in the perforated material is based on treating the perforated material as an equivalent solid material 1 2.
Patenadue et al 2005 evaluated the response of elastomeric blocks under large compression strains and quantitatively measured the nonlinear behavior of rubber compounds under.
For example a square can be deformed into a circle without breaking it but a figure 8 cannot.
And this changes as the deformation becomes larger.
The large displacement solution is required when the acquired deformation alters the stiffness the ability of the structure to resist loads significantly.
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.
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.
25 mm until the onset of damage.
