The obtaining of comprehensive knowledge about the metallic (ferrous and non-ferrous metals) and wood materials structures should be considered as main outcome of the course. After finishing the lectures of the course, students should receive complex knowledge about the macroscopic and microscopic level of these concerned materials. Furthermore, they would become familiar with the main types of wood finishing processes and lumber (timber) products utilized in civil engineering industry.
After the completion of exercises part, students should be able to describe the main parameters and properties of both above mention materials and evaluate the standardized testing methods.
They should be able to understand and explain the influence of moisture action on wood structure with respect to volume changes of wood, additionally to describe sorption process of water binding the cellular structure of the wood. Furthermore, students have to get the knowledge about the production of pig iron, steel and cast iron; how to describe the Fe-C diagram and they should be able to distinguish the steel type according to its labelling and characterize each method of steel heat treatment.

Knowledge of basic, physical-mechanical properties of metals and wood, main products of these materials used in the civil engineering industry, elementary knowledge of wood and metal composition.

Thermal properties

The content of the lectures is prepared in the digital form of presentations with the largest share of graphic details that will allow closer understanding of the objective issue. The content of exercise lectures is based on the digital presentation of tasks, which are then clearly undertaken by experiment. Afterwards, students are asked to compile and evaluate the results in the elaborates.

To successfully complete the exercising part of the course, each student has to submit all finished elaborates that have been continuously monitored during the semester. Furthermore, the exercise lectures have to be ended by successfully passing the final test, which is summarizing the tasks performed during the period. Lecture block may be finished by passing the examination consisting of written and oral parts.
