- Abstract
- In the present contribution, the mathematical analogy existing between the singular
stress field in elasticity due to antiplane loading and the singular electromagnetic
fields in electromagnetism is derived with reference to the problem of isotropic multimaterial
wedges. These configurations, where dissimilar sectors converge to the same vertex,
are commonly observed in composite materials and may lead to singularities. The proposed
analogy permits to extend several elastic solutions for the power of the stress-singularity
already available in the elasticity literature to the analogous electromagnetic problems and
viceversa. Finally, electromagnetic structures that cannot be treated according to the proposed
analogy, such as those related to bi-isotropic multimaterial wedges, are discussed. (literal)
