Experimental and theoretical study of stress relaxation in high-density polyethylene

24th June 2024
No Comment

Abstract Stress relaxation of high-density polyethylene is addressed both experimentally and theoretically. Two types of stress relaxation testing are carried out: uniaxial tensile testing at constant test specimen length and compression testing of a 3D structure producing inhomogeneous deformation fields and relaxation. A constitutive model for isotropic, semi-crystalline polymers is also proposed. The model has […]

Bridging simulation granularity in system-of-systems: conjunct application of discrete element method and discrete event simulations in construction equipment design

18th June 2024
1 Comment

Abstract The paper addresses a critical challenge in System-of-Systems (SoS) simulations arising from the different granularity levels in SoS simulations, integrating non-coupled Discrete Element Method results into SoS-level Discrete Event Simulations using surrogate modeling. Illustrated with a wheel loader bucket use-case in mining, it enhances early design decision-making and lays the groundwork for improving SoS […]

A tradespace exploration approach for changeability assessment from a system-of-systems perspective: application from the construction machinery industry

17th June 2024
No Comment

Abstract The rapid development of new technologies such as electrification, autonomy, and other contextual factors pose significant challenges to development teams in balancing competing aspects while developing value-robust solutions. One approach for achieving value robustness is designing for changeability. This paper presents a tradespace exploration from a Systems-of-Systems perspective to facilitate changeability assessment during early […]
