Module name (EN):
Name of module in study programme. It should be precise and clear.
Dimensioning Components
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Mechanical Engineering, Bachelor, SO 01.10.2024
Module code: MEB_24_M_3.06.BTD
SAP-Submodule-No.:
The exam administration creates a SAP-Submodule-No for every exam type in every module. The SAP-Submodule-No is equal for the same module in different study programs.

MEB_24_M_3.06.BTD (P241-0429) Mechanical Engineering, Bachelor, SO 01.10.2024 , semester 3, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
None.
Recommended as prerequisite for:
Module coordinator:
Prof. Dr.-Ing. Ramona Hoffmann
Lecturer:
Prof. Dr.-Ing. Ramona Hoffmann

Learning outcomes:
After successfully completing this module, students will:
-- be able to distinguish between and describe static and dynamic stresses, especially on real components
-- be able to describe important procedures and tools for component dimensioning
-- be able to take the geometric and material parameters into account that influence the dynamic strength of components -- be able to dimension complex components under composite, multi-axial loads for static and dynamic load cases
-- be able to analyze components with regard to possible instabilities
-- be able to apply energy methods to solve simple problems in elastomechanics
-- be able to formulate questions and speak in front of a large group, as well as expertly justify their decisions in front of groups
Students will improve their subject-related technical English skills. Students will know the subject-specific English terms.
