Aim
The aim of the course is to provide comprehensive knowledge of the most important chapters of elongation measurement and fracture mechanics: Application of elongation stamps; Models of composite specimens; Theory of fracture; The crack tension force; Evaluation methods; Crack propagation stability; Tensile measurements; Vibration of delaminated bars. The course also covers the theoretical and practical issues of simple engineering solutions. The aim is to provide a solid foundation for students completing the subject in their tasks of evaluating measurements and measurement results with models.

He constantly monitors his work, results and conclusions. It expands your knowledge of fracture mechanics through continuous acquisition of knowledge. Open to the use of information technology tools. It seeks to learn about and use novel theories of mechanics. It develops your ability to provide accurate and error-free problem solving, engineering precision and accuracy.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. Accepts well-founded professional and other critical remarks. In some situations, as part of a team, you work with your fellow students to solve tasks. With his knowledge, he makes a responsible, informed decision based on his analyzes. He feels a responsibility to educate the mechanics of the future and to future generations.
Teaching methodology
The subject consists of theoretical and laboratory practice courses of the same size. The understanding of the theoretical materials presented in the lecture is aided by the measurement tasks performed in the laboratory exercises. During the lecture, the most important parts of the material are conducted on a board in order for the joint work to help the students understand the curriculum. The animations and examples projected on the theoretical courses further help to master the curriculum. Materials used in lectures and labs can be downloaded by students. During the semester, several minor diligent homework assignments provide students with extra points. We provide regular consultations during the semester.

General rules
Learning outcomes are assessed on the basis of three mid-year partial performance measurements. Partial performance assessment (homework): a complex way of evaluating the knowledge, ability, attitude, as well as independence and responsibility type competence elements of the subject, the form of which is the individual homework. Measurements made in the group during homework should be individually evaluated and documented in detail. The evaluation is based on the models presented in the presentation.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | formative assessment, simple | |
| Number: | 3 | |
| Purpose, description: | The basic aim of the partial performance assessment is to examine the existence of attitudes and learning outcomes belonging to the autonomy and responsibility competence group. The way to do this is to create two individual homework documents. The topic of the tasks is based on the parts of the material told before the publication. The content and form requirements and evaluation principles of the completed homework are clearly included in the assignment and the website of the subject. You can get up to 20 points with one task. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 100 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 85 % - 90 % |
| good (4) | Good [C] | 70 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 56 % - 70 % |
| sufficient (2) | Pass [E] | 40 % - 56 % |
| insufficient (1) | Fail [F] | below 40 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
Must be present at at least 70% (rounded down) of lectures.
At least 70% of laboratory practices (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| NO | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| The way of retaking or improving a partial assessment for the first time: | ||
| partial assesment(s) in this group cannot be improved or repeated, the final result is assessed in accordance with Code of Studied 122. § (6) | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices may be performed in the teaching term at pre-arranged appointment, non-mandatory | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected upon improved re-submission | ||
