Cranioplasty is the surgical repair of a bone defect in the skull that is left behind after a severe injury or previous operation. It is usually done to protect underlying brain tissue, reduce local pain and to improve the cranial vault aesthetics. Cranial prostheses can be made from different types of materials: autologous bone, titanium, ceramics...

Contraction is a part of a wind tunnel that has the greatest impact on the air flow quality in the test section. The constriction ratio, the cross section shape, the length and wall shape are constructive parameters that influence the uniformity of the flow, the flow turbulence intensity, the flow rotation angularity, the appearance of the flow sep...

The remains of natural and artificial materials in the textile industry are a problem in the technological process because it is a continuous production of waste and related to the need for everyday care. In Bosnia and Herzegovina there are currently no facilities for the material utilization, recycling or reuse of textile waste. Municipal waste di...

The paper presents the volume-of-fluid (VOF) method for interface capturing in free surface flows in OpenFOAM® software. The VOF-model utilises an algebraic compressive scheme to effectively shrink the transitional region between the liquid and the gaseous phase. The capabilities of the model are demonstrated by simulating two-dimensionalaxisym...

The paper analyzes the behavior of the plastic container during the buckling, ie during the load effect on the containers. The analysis was experimentally performed on several different types of containers. The container material is polypropylene. Experimental determination of pressure force and corresponding deformation was performed in thelaborat...

This paper presents the methodology of the FEM modeling of the hook and provides a description of the possibility of tools of the module for structural analysis in the CAD / CAE CATIA system. The tools are described for defining: constraints, loads, shapes and types of contacts on the example of the hook, a lower pulley assembly, for which the FEM ...

This paper deals with the resistance of the shed of a steel hall in Drvar according to technical regulations for snow from 1961 and EC1 regulations. The paper aims to check the reliability of the shed with probabilistic approach. That also implies calibration of the steel hall construction analyzed with classic deterministic method. Statical system...
