Strength of Materials 2 (4 cr)

Evaluation scale

0-5

Objective

To understand the meaning of the strength of materials and stability to dimensioning the steel structures demands the broad understanding of the behavior of structures and the strength of materials. You gain the broad knowledge of strength of materials and you can do static and partly dynamic sizing of the structures with the help of manuals and sizing table cases. You can form a mechanical model from a structure under inspection and you can solve the tensions, stresses and deformations, affecting it. You can also make the stability sizing. You can perceive cases which require more precise and profound strength inspection. You start the studies from the basic concept and proceed to apply them to more challenging calculations of strength of materials.

Knowledge and Understanding:
You understand the principles of strength of materials and how they are based to the statics, mathematics and physics.

Engineering practice:
You can apply the principles of strength of materials to solve practical engineering problems by using the standardized calculation methods.

Investigations and information retrieval:
You are able to make detailed analysis and simulations to strength based problems.

Teaching methods

Lectures and calculation examples. Assignments are based by problem-based learning. As help when you do your assignments you can use your notes from lectures, hand outs, examples and literature. You can do assignments individually or in groups, but you must always return the assignments individually. In calculation lectures you can get help for the assignments from the lecturer or other students.
You must be present at the first lecture (either remotely or face-to-face), and the first assignments must be submitted on time. If the above is not realized, the student will be removed from the course. In the middle of the course, you give anonymous feedback.

Exam schedules

Two smal exams and two resits (all the subjects in resits).

Student workload

Lectures and examples 45 h and independent learning work 63 h. Total 108 h learning work.

Assessment criteria, satisfactory (1)

The grade is defined by exam 90% and homework 10%. In the course there is exam and two resits.

Adequate (1): You are familiar with the basic knowledge and terminology but in dimensioning of basic structures your skills are clearly inadequate. You can solve simple basic problems in an adequate manner.

Satisfactory (2): You are familiar with the basic knowledge and terminology of stresses and strains but in dimensioning of basic structures your skills are inadequate. You can satisfactorily solve simple basic problems.

Assessment criteria, good (3)

Good (3): You are familiar with the knowledge of dimensioning beam and plate structures and you can apply the knowledge acquired to simple structures to solve tensions and strains. You can apply your knowledge to solve tension and strains from basic structures. You also understand those situations which require more precise and profound strength inspection.

Very good (4): You master the essential knowledge of dimensioning beam and plate structures and you can apply the knowledge acquired to basic structures to solve tensions and strains. You also understand those situations which require more precise and profound strength inspection.

Assessment criteria, excellent (5)

Excellent (5): You master the essential knowledge of dimensioning beam and plate structures and you can apply the knowledge acquired in an innovative manner to more challenging structures to solve tensions and strains. You also understands those situations which require more precise and profound strength inspection.
