Stress Concentration around Oval Inclusion in Pull

Abstract

Recently, the influence of the intervention thing by the intervention thing in the structure causes a trouble. Waste lumber was discovered in Hanshin-Awaji big earthquake disaster inside the ferroconcrete leg pillar of the expressway high bridge, and it caused a trouble. The one due at the work that it was mixed in the concrete at the Shinkansen tunnel became a cause, and a concrete lump fell. A report by the experiment is hardly seen though a report by the calculation is seen about the influence by the intervention thing. Nevertheless, it is this research. An influence by tensile load in the elliptic inclusion thing is examined about the object which contains inquiry, an intervention thing. This research can be applied to repression of multiplication of the cancer cell more, and it can think that the convalescence of the cancer patient can be improved.
