Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.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.

Spurious frequencies as a result of numerical boundary treatments [PDF]
The stability theory for finite difference Initial Boundary-Value approximations to systems of hyperbolic partial differential equations states that the exclusion of eigenvalues and generalized eigenvalues is a sufficient condition for stability.

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories
Advanced Engineering Materials, EarlyView.A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials
Advanced Engineering Materials, EarlyView.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 ...

Periodic solutions for 2kth boundary value problem with resonance
Journal of Mathematical Analysis and Applications, 2006 The authors prove existence and uniqueness of periodic solutions to the even-order differential equation in \(\mathbb{R}^N\) \[ u^{(2k)} (t)+\sum^k_{j=1}A_j u^{(2j-1)}(t)+(-1)^{k-1}\nabla G(u,t)=f(t) \] under the assumptions (1) \(A_1, A_2,\dots,A_k\) are symmetric and there exist symmetric matrices \(B_1\) and \(B_2\) and orthogonal matrices \(P_1 ...

Existence of solutions for second-order nonlinear impulsive boundary-value problems
Electronic Journal of Differential Equations, 2009 We prove the existence of solutions for a second-order nonlinear impulsive boundary-value problem by applying Schaefer's fixed point theorem. Results for periodic and anti-periodic impulsive boundary-value problems can be obtained as special cases of
