DOI: 10.1002/nme.6604
Abstract: This article introduces a computational design framework for obtaining three‐dimensional (3D) periodic elastoplastic architected materials with enhanced performance, subject to uniaxial or shear strain. A nonlinear finite element model accounting for plastic deformation is developed,… read more here.

DOI: 10.1002/nme.7211
Abstract: The macroscopic response of short fiber reinforced composites (SFRCs) is dependent on an extensive range of microstructural parameters. Thus, micromechanical modeling of these materials is challenging and in some cases, computationally expensive. This is particularly… read more here.

DOI: 10.1016/j.ijfatigue.2021.106300
Abstract: Abstract In this research, a new life reduction index is proposed for life prediction with the consideration of material’s non-proportional fatigue life reduction process. The new index has been deduced based on the Fatemi-Socie damage… read more here.

DOI: 10.1061/(asce)gm.1943-5622.0000664
Abstract: AbstractAlthough Toyoura sand has been widely used as a standard material for physical model tests (particularly centrifuge model tests), its path-dependent stiffness degradation curves are rarely reported in the literature. This leads to difficulties in… read more here.

DOI: 10.1109/tac.2022.3161381
Abstract: We consider the state and control path-dependent stochastic optimal control problem for jump-diffusion models, where the dynamics and the objective functional are dependent on (current and past) paths of state and control processes. We prove… read more here.

DOI: 10.1109/tcst.2021.3072043
Abstract: In this article, we develop synthesis methods for decentralized control of switched systems with mode-dependent (more generally, path-dependent) performance specifications and apply them to an experimental vehicular testbed. This specification flexibility is important when achievable… read more here.

Abstract: The Kelly criterion determines optimal bet sizes that maximize long-term growth. While growth is definitely an important consideration, the focus on growth alone can lead to significant drawdowns, leading to psychological discomfort for a risk-taker.… read more here.

DOI: 10.3390/g12040093
Abstract: Empirical investigation suggests that conflict is path-dependent, i.e., current conflict leads to more conflict in the future. However, there is very little formal theory for why conflict path dependence exists. We propose a mathematical model… read more here.
