TL;DR: In this article, the authors proposed a hyperelastic J2-flow theory for elastoplastic tangent moduli, which reduces to a trivial modification of the classical radial return algorithm which is amenable to exact linearization.

TL;DR: In this article, an adaptive finite element method is presented for numerical simulation of compressible fluid flow, in which, in addition to refining the mesh in regions where the estimated error is large, the polynomial degree of the elements is increased.

TL;DR: It is shown that in some special but frequently occurring cases, where the Hessian has a speical structure, updating it is not more expensive than updating the gradient vector if a particular factorization of the stiffness matrix is used.

TL;DR: In this article, the concept of an ordered set of optimum designs is introduced and all the design variables and behavioral variables belonging to the optimum designs are represented by successive piecewise Taylor series.

TL;DR: In this paper, a combination of domain splitting, coordinate transformation, and an implicit algorithm is suggested as a versatile three-dimensional program for accurate simulation of geometrically complex environmental flow problems.

TL;DR: In this article, a finite difference dynamic relaxation program for solving plane-strain equilibrium problems in nonlinear elasticity, called chimp, has been proposed, which is suitable for use on personal computers and lends itself readily to vectorization.

TL;DR: In this paper, a finite element algorithm for analysis of stiffened plates by normal mode approach under stationary random stochastic loading has been presented, which is applicable to thin as well as thick plates.

TL;DR: By means of the weighted residual method, a general form of linear multistep methods is developed for time-dependent vibrating systems and a feasible two-step method is then obtained as discussed by the authors.
