Ellipsoidal characterization of neutral inclusions for imperfect bonding of high-conductivity type

Junyong Eom, Shota Fukushima, Yong-Gwan Ji +3

This paper concerns neutral inclusions for imperfect bonding of high-conductivity type. An inclusion, which is a bounded domain, is said to be of imperfect bonding of high-conducti…

Finiteness of the stress in presence of closely located inclusions with imperfect bonding

Shota Fukushima, Yong-Gwan Ji, Hyeonbae Kang +1

If two conducting or insulating inclusions are closely located, the gradient of the solution may become arbitrarily large as the distance between inclusions tends to zero, resultin…

A fast and efficient numerical method for computing the stress concentration between closely located stiff inclusions of general shapes

Xiaofei Li, Shengqi Lin, Haojie Wang

When two stiff inclusions are closely located, the gradient of the solution to the Lamé system, in other words the stress, may become arbitrarily large as the distance between two…

Asymptotic analysis of the Narrow Escape Problem in general shaped domain with several absorbing necks

Xiaofei Li, Shengqi Lin

This paper considers the two-dimensional narrow escape problem in a domain which is composed of a relatively big head and several thin necks. The narrow escape problem is to comput…

Neutral inclusions, weakly neutral inclusions, and an over-determined problem for confocal ellipsoids

Yong-Gwan Ji, Hyeonbae Kang, Xiaofei Li +1

An inclusion is said to be neutral to uniform fields if upon insertion into a homogenous medium with a uniform field it does not perturb the uniform field at all. It is said to be…

Polarization tensor vanishing structure of general shape: Existence for small perturbations of balls

Hyeonbae Kang, Xiaofei Li, Shigeru Sakaguchi

The polarization tensor is a geometric quantity associated with a domain. It is a signature of the small inclusion's existence inside a domain and used in the small volume expansio…
