Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

open access: yessteel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

open access: yesSafety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

open access: yesSafety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

The uncertainty of sound insulation properties of light weight building elements

open access: yes, 2014
Measurement uncertainty is an important topic in building acoustics measurements carried out in the field assessing the sound insulation between rooms as well as conducted in test stands characterizing the sound insulation properties of a building element accurately. Beyond measurement method related contributions to the uncertainty budget there is the
