MEK/FAM
Section for Solid Mechanics is responsible for
DTU’s teaching and research in the area of mechanics
of materials and structures. Using computer
modeling, experimental techniques, and
purely theoretical methods, we devote particular
focus to the sub-areas of micro mechanics; fracture
mechanics; statics and dynamics of structures;
metal forming; nonlinear dynamical phenomena;
machine elements and mechatronics;
and topology- and shape optimization of structures
and mechanisms.
Solid Mechanics forms a fundamental branch of
engineering science, supplying methods and
tools for the prediction of loads, deformation, and
damage for all kinds of materials and structures
– from micro machines and organic tissue, over
cars and turbines, to ships and oil rigs.
Section for Solid Mechanics is internationally
recognized for its activities, and hosts leading
experts within several research areas. We cooperate
with partners at leading international universities,
and with Danish industry and research
institutions.

Master Thesis Project at
MEK / Solid Mechanics
We offer master thesis projects within the following
major areas:
• Strength of Materials and Structures
• Dynamics and Vibrations
• Optimal Structures and Mechanisms
• Machine Elements and Mechatronics
Please take the below project titles as indicative of
the interests of the individual supervisors, and as a
starting point for negotiating a more detailed project
proposal. Note also that you, the project, and
the supervisor should make up a “proper match” –
promoting your chances to develop and excel personally
and professionally during the project period.
Be prepared that a supervisor may propose
other projects that better suit your qualifications, or
the supervisor’s present activities.
Many projects at Solid Mechanics emerge from
a students desire to dwell deeper into a particular
field, for which the supervisor then suggests a project.
Others spark off from collaboration with industry
or institutions outside DTU. And, of course, it’s
always an option to suggest a project yourself to a
suitable supervisor. In any case, if you are prepared
to take part in the daily life with the staff and
students – and to work seriously and with enthusiasm
on your project – we will be happy to welcome
you at Solid Mechanics.
