We study an iterative differential-difference method for solving nonlinear least squares problems, which uses, instead of the Jacobian, the sum of derivative of differentiable parts of operator and divided difference of nondifferentiable parts. Moreover,

A generalization of order convergence
Let $E$ be a sublattice of a vector lattice $F$. $\left( x_ \right)\subseteq E$ is said to be $ F $-order convergent to a vector $ x $ (in symbols $ x_ \xrightarrow{Fo} x $), whenever there exists another net $ \left(y_ \right) $ in $F $ with the some index set satisfying $ y_ \downarrow 0 $ in $F$ and $ | x_ - x | \leq y_ $ for all indexes $ $.

Two-Scale Convergence of First-Order Operators
Nguetseng's notion of it two-scale convergence and some of its main properties are first shortly reviewed. The (weak) two-scale limit of the gradient of bounded sequences of W^{1,p}(\mathbb R^N) is then ...

Evaluating Energy Absorption Performance of Filled Lattice Structures
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

On Generalized Statistical Convergence of Order of Difference Sequences
We introduce the concept of statistical convergence of order of difference sequences, and we give some relations between the set of statistical convergence of order of difference sequences and strong -summability of order .

In this manuscript, a new family of Jacobian-free iterative methods for solving nonlinear systems is presented. The fourth-order convergence for all the elements of the class is established, proving, in addition, that one element of this family has order

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Eigenvalue homogenization for quasilinear elliptic equations with various boundary conditions
We study the rate of convergence for (variational) eigenvalues of several non-linear problems involving oscillating weights and subject to several types of boundary conditions in bounded domains.

Higher-Order Iteration Schemes for Solving Nonlinear Systems of Equations
We present a three-step family of iterative methods to solve systems of nonlinear equations. This family is a generalization of the well-known fourth-order King’s family to the multidimensional case.

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials
This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...
