Manufacturing tolerant topology optimization

Manufacturing tolerant topology optimization was researched by Ole Sigmund (link). Especially MEMS manufacturing techniques are considered like i.e. etching, e-beam lithography and laser machining. Over-etched and under etched structures were demonstrated by eroded and dilated structures. Then sensitivity analysis was … Continue reading

AXIOMATIC APPROACH FOR STRESS RELAXATION IN AUTOMOTIVE MULTI-SHELL-STRUCTURES

This article is related to a rather weird optimization technique (link). To be honest I did not know much about axiomatic design approach before reading it. And I did not like what I have seen. I will not write about … Continue reading

Optimization of the Die Topology in Extrusion Processes

This study topology (or rather shape) optimization of extrusion dies were examined (link). Two aspects were optimized, reduction of dead zones and flow speed equalization. Interestingly the dead zone reduction was done by hand, in a systematic way. Flow speed … Continue reading

Off-Topic: Atomistic Simulation Game

You can play the Atomistic Simulation Game (or applet) that I recently made using Unity 3D. It is an atomistic simulation, that utilizes Lennard-Jones potentials. I simplified some aspects, so that it can be run like a game in real … Continue reading

BLAST MITIGATION USING HYBRID CELLULAR AUTOMATA

This study investigates topology optimization using Hybrid Cellular Automata (link) for blast mitigation. A metal-ceramic composite armor structure is developed, that reduces accelerations felt by the occupant. It is reported that the optimization did not converge, however still the results … Continue reading
