Thermomechanical modelling of sandwich panels with connections in fire resistance tests

This paper presents two full-scale fire resistance tests of sandwich panels with connections, to verify one way coupled fire-structure simulations. The heat transfer simulations agree well with the tests, however, the structural response simulations show some differences compared to the start of the first test, which is a sandwich panel façade....

A two-scale FE model to address connections in coupled fire-structure simulations

A two-scale finite element model is proposed to improve two-way coupled fire-structure simulations. The model consists of (i) a global-scale model, which accounts for the structure, and (ii) a small-scale model for each connection. Structural parts on the global scale are connected by spring elements, which stiffness properties are updated by...

Experimental assessment and model development of FRP sandwich panels subjected to out-of-plane impact loading

Fibre reinforced composites are lightweight, strong materials that are increasingly used in all sorts of applications. When loaded in-plane, the material is very strong due to the profitable properties of the fibres. Therefore, the design is normally such that the predominant loading condition is in-plane. However, out-of-plane loading is not...

Development of Dynamic Loudspeakers Modified as Incident Pressure Sources for Noise Reductiuon in a Double Panel Structure

This paper presents a modified loudspeaker source for decentralized feedback cavity control in a double panel structure to reduce the noise transmission. The double panel structure con-sists of two panels with air in between and offers the advantages of low weight, low sound transmission at high frequencies, and thermal insulation. The main...
