Aim
The aim of the course is to provide comprehensive knowledge of the most important chapters of continuum mechanics: Tensor algebra; Tensor analysis; Kinematics of continuums; Voltage tensioners; Speed status of continuums; Objective derivatives; Basic mechanical laws; Energy items. The course covers both theoretical and practical issues of hyperelastic material modeling. The aim is to provide students with a solid foundation in subsequent material modeling and nonlinear finite element calculations.

In some situations, as part of a team, you work with your fellow students to solve tasks. With his knowledge, he makes a responsible, well-founded 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 practical courses of the same size. Numerical examples solved in the exercises help to understand the theoretical materials presented in the lecture. 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. The materials used in the lectures and exercises can be downloaded by the 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 four mid-year written performance measures (two partial and two summative learning assessments). Summarizing academic performance evaluation: a complex, written way of evaluating the competence-type competence elements of the subject and knowledge in the form of an indoor dissertation, the dissertation focuses on the application of the acquired knowledge, so it focuses on problem recognition and solution, on the other hand, asks for the necessary lexical knowledge during the performance appraisal, the working time available is 90 minutes; 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.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 2 | |
| Purpose, description: | Summative assessments collectively examine and assess students ’learning outcomes defined by knowledge and ability type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge as well as the existence of the knowledge and skills acquired in practice. Each summative assessment focuses 50% on theoretical knowledge and 50% on application skills. They will be completed on the date specified in the academic performance assessment plan, expected to be in the 8th and 14th weeks of education. Each of the two summary performance evaluations can score 35-35 points. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, simple | |
| Number: | 2 | |
| Purpose, description: | The basic goal of 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. A maximum of 15 points can be earned 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 | 70 % |
| Mid-term assessment No. 2 | 30 % |
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

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).
| Need mid-term assessment to invidually complete? | ||
| yes | ||
| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| NO | ||
| The way of retaking or improving a summary assessment for the first time: | ||
| each summative assessment can be retaken or improved | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| retake or grade-improving exam possible for each assesment separately | ||
| 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) | ||
