Design Technology 3

Module name (EN):
Name of module in study programme. It should be precise and clear.
Design Technology 3
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Mechanical Engineering / Production Technology, Bachelor, ASPO 01.10.2021
Module code: DBMAB-250
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.
P720-0013, P720-0014
Hours per semester week / Teaching method:
The count of hours per week is a combination of lecture (V for German Vorlesung), exercise (U for Übung), practice (P) oder project (PA). For example a course of the form 2V+2U has 2 hours of lecture and 2 hours of exercise per week.
-
ECTS credits:
European Credit Transfer System. Points for successful completion of a course. Each ECTS point represents a workload of 30 hours.
5
Academic Year: 2
Mandatory course: yes
Language of instruction:
German
Assessment:
2 exams consisting of a graded written examination and a graded term paper
  • Graded exam (Duration 90 min., 100 pts.)
    The exam will be written in the 3rd semester (Block 3B) according to the examination schedule.
  • Graded term paper (100 pts.)
    The topic will be a task related to Machine Elements 2 and 3. It will be handed out on the first working day of the 1st week of Block 4B (4th semester).
    The term paper is an exam component comprising 30 hours, to be completed within a period of 60 working days (Mon-Fri except public holidays) from the date on which the topic is issued.
 
Prerequisites for receiving credits:
The achievement of at least 40 out of 100 points in the module exam.
The achievement of at least 40 out of 100 points for the term paper.
 
The module grade is calculated as follows:                 
Exam: 80%         
Term paper: 20%
 
The grade will be shown as a decimal grade according to the htw saar grading scheme.

Learning outcomes:
After successfully completing this course, students will expand their knowledge of the basic stresses on "buckling and centric buckling". They will be able to assess the stability of equilibrium positions of compression loaded members and determine the critical load for the buckling of members. In addition, they will be able to apply the strength hypotheses to carry out the stress verification for multi-axial loading and dimension the component by comparing the comparative stress and the material parameters. They will be able to determine the appropriate failure hypothesis (ductile and brittle fracture, fatigue fracture, deformation) and select, calculate and design machine elements of rotary motion (axles, shafts, bolts, journals, plain and roller bearings, couplings and brakes) and gears.  
 
Students will be able to work independently and using scientific means on an interdisciplinary task of intermediate complexity (linking technical mechanics, construction and materials technology) for the calculation/dimensioning and design of machine elements.
