#### In programs

TIMEL MECHATRONICS ENGINEERING, Year 3 (compulsory)

#### Theme:

Environment 1,0 hec

#### Course specific prerequisites

The courses LMA401 Calculus, MVE580 Linear algebra and differential equations, TME221 Mechanics and LMT212 Mechanics, advanced course, or equivalent.

#### Aim

Combination of materials and shapes to achieve an optimal component, based on lightweight design or multifunctional properties, characterizes modern engineering technology. To be able to optimize the material choice while securing stiffness and strength, a basic understanding of the mechanical material behavior is necessary.

The aim of the course is to give you insight into mechanical behavior for polymers, composites and metals. The characteristics of each material class will be studied with respect to the choice of material or material combination. The course gives you both strength of materials and materials technology perspectives on stiffness and strength at different stress/temperature conditions.

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

Strength of materials:
• Define and describe “stress”, “strain” and “equilibrium” for a solid component,
• describe and define isotropic elastic- and thermoelastic material behavior,
• set-up and solve the mathematical models for a uniaxial bar and a torsion loaded shaft,
• calculate internal forces, stresses and strains for a uniaxial bar and a torsion loaded shaft from the relevant boundary conditions and loading,
• from the relevant boundary conditions and load, numerically solve multiaxial elasticity problems using the finite element method,
• motivate and compute principal stresses,
• motivate and use von Mises yield condition for metallic materials.
Materials technology:
• Describe the choice of material and shape for optimal properties of the component,
• define and describe the most important material properties,
• be able to group different materials into material groups; describe the most important properties of the material groups,
• describe the most important material forming technologies for different material groups,
• be able to perform a material selection for a component,
• determine the mechanical properties that set the design of a component (stiffness, plasticity, fracture properties); use material indexes to optimize the material selection.
• describe and assess the environmental impact of a material; make a sustainable choice of the material,
• describe the most common construction materials, their properties, with pros and cons, in different applications.

#### Content

Strength of materials:

Uniaxial conditions: The bar problem. Tensile/compressive stress and strain. Hooke's law and equilibrium. Torsion. Shear stress and strain. Hooke's law and equilibrium. Temperature effect.
Multiaxial conditions: Multiaxial stress and strain. Principal stresses. Hooke's generalized law. Plane stress and strain. Equilibrium. Introduction to the finite element method. Yield conditions.

Materials technology:

The relationship between material and form. The relationship structure, process and properties. Material properties. Material groups. Material processing and forming methods. Material selection methodology. Material index. Stiffness. Material yield and failure. Temperature. Sustainability and environmental considerations. Price. Knowledge of metals, polymers, ceramics, and composites.

#### Organisation

The learning activities consist of lectures and exercises, with coordinated examples and project assignments. The project focuses on material selection and has assignments involving finite element analysis.

#### Literature

To be communicated later on the course homepage.

#### Examination including compulsory elements

The course is examined through the project and a final written exam. The project can give bonus points to the exam.

Grading TH (U, 3, 4, 5).

The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
