MAE3407
Aircraft Structures II
This unit aims to develop an understanding of the analytical methodologies used in strength and stiffness
assessment of aircraft structures. The unit will develop an understanding of the translation of aerodynamic
and ground loading on aircraft wings and fuselage to the overall airframe. An understanding of the concept
of structural idealisation and constraint will be developed along with real-world limitations. The principles of
stressed skin construction will be considered in detail. The unit aims to develop an understanding of the
analysis and design of structural problems common in the aerospace industry. It will provide students with
the tools necessary to analyze aircraft structures.

Your Feedback to Us
Monash is committed to excellence in education and regularly seeks feedback from students,
employers and staff. One of the key formal ways students have to provide feedback is
through the Student Evaluation of Teaching and Units (SETU) survey. The University’s
student evaluation policy requires that every unit is evaluated each year. Students are
strongly encouraged to complete the surveys. The feedback is anonymous and provides the
Faculty with evidence of aspects that students are satisfied and areas for improvement.
For more information on Monash’s educational strategy, see:
www.monash.edu.au/about/monash-directions/directions.html and on student evaluations,
see: www.policy.monash.edu/policy-bank/academic/education/quality/student-evaluationpolicy.html

Teaching and Learning Method
The unit consists of lectures and practice classes with some computer laboratory classes.
Tutorial allocation
There are 2-hours of practice/ laboratory classes scheduled each week, commencing in week
2. The coordinator will be allocating students to the various groups. Students not allocated to
a particular practice class will not be accepted into that session without the written consent of
the unit coordinator.
Communication, participation and feedback
Monash aims to provide a learning environment in which students receive a range of
ongoing feedback throughout their studies. In this unit it will take the form of group
feedback via practice classes, individual feedback, peer feedback, self-comparison, verbal
and written feedback, discussions in class, as well as more formal feedback related to

Assessment Tasks
Participation
Participation of all assessment tasks is expected for all students. Failure to complete any of
the tasks satisfactorily will result in lowering of the overall grades in this unit.
Assessment Task 1:
Practice classes
Details of task: Students will be presented with a set of practice questions at each tutorial
session. These questions are to be completed with the help of tutors in the session and
submitted before the end of the session. The assessment will be marked and returned to the
student at the next tutorial session.
Criteria for Assessment task:
This practice questions evaluate the progress of students in keeping up with lecture materials
and will be graded according to correctness of the answers given.
Requirements
Grades will only be given to answers handed in during tutorials (which is compulsory).
Students who are unable to attend the tutorial for a valid reason must hand in the answers
before the end of the week (Friday) together with a letter explaining absence to the mailbox of
the lecturer in order to have them graded.
