Modelling and simulation are important tools during design development processes. For accurate predictions of, e.g. manufacturing processes or final product performance, reliable material data is needed. Usually, the applied models calibrated by utilising direct methods such as conventional uniaxial tensile/compression tests but also inverse occasionally applied. Recently, an effective method, ...

In Burkholderia cenocepacia H111, the large surface protein BapA plays a crucial role in the formation of highly structured communities, known as biofilms. We have recently demonstrated that quorum sensing (QS) is necessary for the maximal expression of bapA. In this study we identify BapR, a protein from the IclR family of transcriptional regulators that, in conjunction with QS, controls biofi...

recently, offshore and ocean engineering have been dealing with novel materials that play a significant role in reducing the weight of structures used in the ship construction industry. 5xxx series of aluminum alloys are of the novel alloys are suitable for construction of ship hulls and the topside structures of offshore platforms. within different 5xxx aluminum alloys, aa5083 is of great impo...

The paper deals with the laser welding of thick-walled plates a thickness 20 mm made EN AW5083-H111 aluminum alloy. A simulation model for analysis process is developed and verify using temperature measurement during experimental samples by TruDisk 4002 device. Based on numerical in ANSYS program code, suitable parameters production high-quality weld joints were suggested. For at speed 10 mm.s ...

In this study, we investigate the influence of Sc microalloying on microstructure Al5083 alloy. Trace amounts addition drastically improve mechanical properties alloy from 216 MPa to 233 MPa. Macroscopically, significantly reduces grain size Al by approximately 50%. Additionally, a microstructural investigation reveals that element induces fine Al3Sc nanoprecipitates in matrix. The formation re...
