In this paper, a  fuzzy numerical procedure for solving fuzzy linear Volterra integro-differential equations of the second kind under strong  generalized differentiability is designed. Unlike the existing numerical methods, we do not replace the original fuzzy equation by a $2times 2$ system ofcrisp equations, that is the main difference between our method  and other numerical methods.Error ana...

Third-order numerical methods are analyzed for secular equations. These equations arise in several matrix problems and numerical linear algebra applications. A closer look at an existing method shows that it can be considered as a classical method for an equivalent problem. This not only leads to other third-order methods, it also provides the means for a unifying convergence analysis of these ...

Several widely-used textbooks lead the reader to believe that solving a linear system of equations Ax = b by multiplying b by a computed inverse inv(A) is inaccurate. Virtually all other textbooks on numerical analysis and numerical linear algebra advise against using computed inverses without stating whether this is accurate or not. In fact, under reasonable assumptions on how the inverse is c...

this paper is on the elasto-plastic analysis of plane stress problems. a five-parameter yield surface is presented. this yield criterion uses associate flow along with mixed hardening rule. the analytical formulations are written and related computer program for non-linear analysis is prepared. finally, based on the formulations, numerical examples are solved.
