"This paintings develops the method in response to which sessions of discontinuous features are utilized in order to enquire a correctness of boundary-value and preliminary boundary-value difficulties for the circumstances with elliptic, parabolic, pseudoparabolic, hyperbolic, and pseudohyperbolic equations and with elasticity conception equation structures that experience nonsmooth strategies, together with discontinuous ideas.

36). σi j are usually referred to as the“generalized stresses” and are not stresses in the strict sense. 75), these quantities are based on the element volume before deformation. However, they have important symmetry characteristics that are missing in σi j , namely, σi j = σ j i (while σi j = σ j i ). Therefore, under a coordinate system transformation the tensor σ = {σi j } acts like a secondorder symmetric tensor. Subsequently, this tensor should be regarded as the stress tensor when a fully nonlinear analysis is employed.

In-plane) force component will be denoted “T”. Both N and T are functions of the location of the circle over the plane (or essentially the location of its center point, P in the plane). By narrowing the area A, the point P and the area A collide, and the normal and tangential stress components at P are defined as N , A→0 A σN (P) = lim T . 72) Hence, the dimension of the stress components is force per unit area. At each point, one may examine an infinitesimally small material element, as shown in Fig.
