Learning outcomes of the course unit
The course enables students to gain practical experience with calculation by help of finite element method with focus on aircraft structures.
Prerequisites
Basic knowledge of math, solid mechanics and material strength.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Condition for the course-unit credit award is to deliver a FEM project by required deadline. Work evaluation is made with each student individually and marked according to the valid scale.
Aims
Aim is to acquaint students with finite element method and its use in strength calculations of aircraft structures.
Specification of controlled education, way of implementation and compensation for absences
Lecturers linked with seminars are compulsory (minimal participation 80%). Reasoned absence can be compensated by consultations.
