Abstract [en]

An experimental study regarding a model material's ability to absorb energy during blasting has been carried out. The tests were performed using copper pipes with a wall thickness of 5,0 mm and an inner diameter of 100 mm. An inner layer of mortar was cured inside the copper pipes, reducing the inner diameter to 44,5 mm. The plastic explosive NSP 711 was used for the tests, which from our viewpoint is considered to detonate ideally. The displacements of the copper pipe were registered at several locations during the tests.FEM simulations were conducted based on the test set up, and the calculated displacements of the copper pipe were compared with the displacements obtained from the tests. The input data for grout and copper in the simulations were adjusted until a fair agreement was obtained between simulation results and test data. The simulations are thereafter used to estimate the transmitted energy to the mortar and the copper pipe.

Abstract [sv]

En experimentell studie har genomförts avseende ett modellmaterials förmåga att uppta detonationsenergi vid sprängning. Försöken har genomförts med kopparrör med godstjockleken 5,0 mm och inre diametern 100 mm. Rören har fodrats med finpartikelbetong, varvid den inre diametern reduceras till 44,5 mm. Explosivämnet NSP 711 har använts vid försöken vilket ur vår synpunkt kan anses ge en ideal detonation. Vid försöken registreras kopparrörets förskjutningar i ett flertal punkter.FEM-simuleringar har genomförts för försöken, varvid de registrerade förskjutningarna för kopparrören jämförts med förskjutningar beräknade vid simuleringarna. Indata för finpartikelbetong och koppar anpassas sedan tills en acceptabel överrensstämmelse uppnåtts. Energiomsättning vid försöken har därefter uppskattats baserat på simuleringsresultaten.
