Eligibility

General entry requirements for bachelor's level (first cycle)
Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling the requirements above.

Specific entry requirements

The same as for the programme that owns the course.
Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling the requirements above.

Course specific prerequisites

Mathematics (linear algebra, differential equations and integrals) and mechanics (statics).

Aim

The main aim is to give the student a fundamental engineering knowledge about the design of constructions. Therefore an understanding of terminology, methods and limitations used in the engineering discipline strength of materials is needed as well as a capability to solve smaller design problems. Further, it is important to judge whether the solution of the problems are reasonable and to be able to predict function and reliability of constructions.

Learning outcomes (after completion of the course the student should be able to)

  • understand fundamental quantities such as forces, deformations, stresses, strains, compatibility, critical loads 
  • understand the importance of constitutive equations and apply elasticity, thermo-elasticity and ideal plasticity
  • evaluate forces, stresses, deformations and strains on structures and components made up of basic elements such as bars, shafts, beams and pipes
  • estimate the risk of failure, in particular due to buckling, fatigue, plastic deformation and fracture
  • evaluate and explain the importance of principal stresses/strains and effective stresses/strains
  • design and evaluate mathematical models of the real-life structures modelled as a combination of basic elements such as bars, shafts, beams and pipes
  • estimate the accuracy of these models, in particular regarding if all possible failure modes that are captured, and judge whether a more sophisticated model is needed
  • understand basic concepts of more advanced topics in solid mechanics, such as finite element simulations, dynamic systems, design philosophies, contact mechanics etc

Content

The course contains the following parts:
  • determination of deformations, strains, internal forces and stresses for: tension/compression of bars, torsion of circular shafts and thin-walled cross-section, bending of beams
  • instability of columns
  • constitutive equations such as Hooke's law under uniaxial and multiaxial conditions, thermoelasticity and ideal plasticity
  • multiaxial stress and strain conditions; in particular principal stresses and effective stresses
  • stresses and strains in thin-walled cylindrical and spherical pressure vessels
  • fatigue and fracture analysis
  • an overview of more advanced topics in the field of solid mechanics

Organisation

Lectures, tutorials, and supervised problem-solving.
