Fast Stiffness Matrix Calculation for Nonlinear Finite Element Method
We propose a fast stiffness matrix calculation technique for nonlinear finite element method (FEM). Nonlinear stiffness matrices are constructed usingGreen-Lagrange strains, which are derived from infinitesimal strains by adding the nonlinear terms discarded from small deformations. We implemented a linear and a nonlinear finite element method with the same material properties to examine the di...
متن کاملFinite element modeling of polymer matrix nano-composites reinforced by nano-cylindrical fillers
A new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. The total elastic modulus of nano-composite is evaluated. Numerical results are in good agreement with the previous proposed theoretical modeling. Higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.
متن کاملFinite-element Geometric Stiffness Matrix Lumping by Numerical Integration for Stability Analysis
Using numerical integration in the formulation of the finite-element geometric stiffness matrix and placing movable nodes at integration points causes the geometric stiffness matrix to become lumped or diagonal. The consistent geometric stiffness matrix which is a non-diagonal matrix, is normally used in the finite-element eigenvalue buckling problem. Altering the method to deliver a diagonal (...

متن کاملTrace Element Variation in Carbonaceous Chondrite Matrix
Introduction: Chondrite matrix is defined as 'the fine-grained, predominantly silicate, material intersti-tial to macroscopic, whole or fragmented, entities such as chondrules, inclusions and large isolated mineral (i.e., silicate, metal, sulphide and oxide) grains' [1]. Matrix materials are derived from a wide variety of sources: presolar grains, solar-nebular condensates, and finely ground li...
