Vehicle occupant restraint system design under uncertainty by using multi-objective robust design optimization
The Multi-Objective Robust Design Optimization (MORDO) is employed for the vehicle occupant restraint system design. The optimization aims to improve the safety performance of the system and its robustness simultaneously.
Multidisciplinary optimization of the thermal and structural model of a building
Building energy performance largely depends on facade design and local weather characteristics. modeFRONTIER has been used - together with Rhino/Grasshopper plugin - to maximize winter radiation and minimize structural mass of a office building floor located in Toronto, Canada.
Process Integration and Optimization of ICME Carbon Fiber Composites for vehicle lightweighting: a preliminary development
Different from the Sheet Molding Compounds (SMC) structure, the unidirectional (UD) structure (laminate) has multiple layers, and each layer has anisotropic properties. The layout of each component in the vehicle structure needs to be optimized in order to achieve the optimum structure performance such as stiffness, durability, NVH, and safety. he multi-layer UD structure optimization is implemented on the platform of modeFRONTIER.

Multiobjective Sizing Optimization of a Steel Girder Bridge with a Simple Target–Driven approach
The structure considered in this study is a bridge consisting of four identical and equally–spaced steel girders with ﬂanges welded to the web. The beams are supposed to bear a concrete slab, an asphalt layer and two sidewalks. A reference optimization is performed by using the modeFRONTIER MOGA-II algorithm in order to find a series of compromise solutions between small seismic horizontal displacements and small weight values.
Optimization of a conveyor transfer chute including particle flows
A common problem in the transfer chute is the unbalanced mass flow at the outlet conveyor. The objective consists in reducing the difference in curve averages of total mass in left and right part of the conveyor. Coupling Rocky DEM with modeFRONTIER enabled engineers to select the optimum design that reduced this difference to 0.2%.
INVERSE DERIVATION OF CONSTANTS FOR THE CONSTITUTIVE EQUATION AND FATIGUE MODEL OF PB-FREE SOLDER JOINTS BASED ON EXPERIMENT RESULTS, FINITE ELEMENT SIMULATION AND VIRTUAL OPTIMIZATION METHODOLOGY
A novel approach of deriving the constants for lead free solder creep constitutive equation and fatigue model has been proposed in this paper. In this approach, the constitutive parameters and fatigue model constants were determined retrospectively based on the test results of selected lead-free BGA packages, multi-objective optimization, and finite element modeling. ANSYS and modeFRONTIER are coupled in this methodology.
Parameterization and Multi-objective Optimization
This thesis aims to optimize a control arm of a car with multiobjective optimization methods based on NX and modeFRONTIER. The study attempts to identify the best algorithms for the design considering given requirements. The overall goal is to reduce weight while maintaining the same stiffness.This research is done as a contribution to the SupLight EC research project.
Scaling Parameter for Fatigue Delamination Growth in Composites under Varying Load Ratios
The aim of this paper in aerospace applications, is to develop a scaling parameter that can account for the effects of fiber bridging on the growth behavior of delamination cracks under fatigue loading. An inverse method has been developed to determine the traction stresses acting in the crack wake. Static and fatigue experiments were carried out on IM7/977-3 composite laminates.
