Development of a viscoplastic-damage model for creep-fatigue FE-calculations of the lead-free SnAgCu solder alloy for automotive applications

open access: yes, 2019
Automotive electronic devices are exposed to substantially harsher thermomechanical loads compared to commercial consumer electronic products. Inside an electronic device, there is a large number of solder joints, supporting the electrical as well as the

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

The Time Development of the Microstructural Properties of Plastic Concrete: Material Insights and Experimental Boundaries

open access: yesConstruction Materials
Plastic Concrete is a low-strength (fcm,28d ≤ 1.0 MPa), low-stiffness impervious concrete used for cut-off walls in earthen dams worldwide. These properties are achieved through a very high w/c ratio (w/c ≥ 3.0) and water-binding additions (e.g ...

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

open access: yesAdvanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Modification of QDs with MPA.

open access: yes, 2015
(a) Zeta potential of MPA-QDs and QDs. The QDs surface had no charge, but this surface became negative after modification with MPA; (b) Gel electrophoresis of MPA-QDs and QDs in the presence of an electric field.
