    摘要: When an integrated displacement amount of the particles constituting a contact candidate pair is equal to or more than ¼ (one-quarter) cell or more, likelihood becomes high that the particles of the contact candidate particle pair, which was not in contact with each other, would come into contact with each other. Then, in such high likelihood, data relating to contact candidate particle pairs are updated. With this arrangement, even if contact candidate particle pair data updating is decimated and part of contact determination is accordingly omitted to increase a computing speed of the contact determination, accuracy of simulation will not be reduced. Thus, according to the present invention, the computing speed of the contact determination can be increased without lowering the accuracy of simulation.

    摘要: There are provided a method by which a stress history of an object can be measured with high reliability if the object, which has temporarily been elastically deformed upon receiving an external force, recovers from the elastic deformation, and a composite material containing cement as a main component, of which a stress history can be measured with high reliability without reducing the strength of the material itself and without breaking the structure. To achieve the above-mentioned advantages, the method includes the steps of: acquiring an initial value of a twin density for calcite particles contained in an object to be measured that is elastically deformable upon receiving an external force; and measuring a history of stresses received by the object to be measured on the basis of a difference from the initial value in respect of the twin density for the calcite particles after the object to be measured receives the external force. The composite material includes calcite particles, for which a twin density is known and which are mixed to be distributed in the material, partially replacing an aggregate of the material.
