This article is aimed to introduce a new hybrid analytical-digital technique for solving a wide range of problems in fluid mechanics. This method is according to the Different Transform Method (DTM) and Newton’s Iterative Method (NIM). In the Boundary Value Problems (BVP), the system and the boundary conditions converted to an algebraic equation set, and the Taylor series of the solution are subsequently calculated. By finding Jacobian matrix, the unknown parameters of the solution may be calculated using the multi-variable iterative Newton's method. The techniques are employed to determine a proximate solution for the problem. To expound upon the application of the new hybrid method illustratively, two nonlinear problems in fluid mechanics are considered: condensation film on the inclined rotating disk and the rotating MHD flow on a porous shrinking sheet. Using comparing the present results obtained with the numerical solutions and results presented in the literature, an excellent accuracy is observed. Quick convergence of the solution is another important merit of the proposed method.

Designer of military and high-security facilities, planner, architects and engineers throughout the world are much concerned against a blast load on structures. Blast load is a human hazard occurring in the world, due to terrorist, chemical explosives, mining area, an accident, and so on. Blast load is an unpredictable load occurring. The blast load occurs in a few seconds. The blast load does not only lead to structural but also take the life of occupations. In this study five – storey unsymmetrical structures exposed to blast load are considered. The three different control devices are considered such as cladding material, base isolation with lead rubber bearing (LRB) and MR Damper. Cladding material will absorb energy after the severe pressure release from the blast and then transfer less amount of energy to the structures. Base isolations with lead rubber bearing not only absorb energy but also increase the stiffness of the structure. Among the different devices’ MR Damper plays a vital role reduce the considerable amount of responses.
