METHOD FOR CREATING FINITE ELEMENT MODEL FOR FILLER-CONTAINING RUBBER

摘要

An objective of the present invention is to provide a method for creating a finite element model for a filler compounded rubber that can reduce the time and effort involved in creating the model. Provided is a method of using a computer to create a finite element model for a filler compounded rubber wherein a filler is dispersed in a rubber matrix, said method comprising a first step of defining a filler model wherein filler is discretized using a finite number of elements, a second step of defining, separately from the filler model, a rubber matrix model wherein at least the space occupied by the rubber matrix is discretized using a finite number of elements, and a model embedding step of overlaying the rubber matrix model and the filler model and imparting a constraint to at least a boundary between the filler model and the rubber matrix model to define a filler compounded rubber model.

1. A method for creating a finite element model of a filler compounded rubber comprising a filler dispersed in a matrix rubber using a computer, the method comprising:
a first step of defining a filler model in which the filler is discretized using a finite number of elements; a second step of defining a matrix rubber model independently of the filler model, the matrix rubber model being created by discretizing a space in which at least the matrix rubber occupies using a finite number of elements; and a model-embedded step of embedding the filler-model in the matrix rubber model, wherein the model-embedded step comprises a step of overlapping the filler-model with the matrix rubber model without considering sharing of the respective nodes of the filler model and the matrix rubber model, and a step of defining a filler compounded rubber model by providing a constraint condition to at least a boundary between the filler model and the matrix rubber model.
