Learning outcomes of the course unit
Students will master to formulate the state of stress and deformation in tensor recontouring. Background knowledge of tensor counting. Formulation of tensor quantities in subscript expressions. Theory of plasticity, conditions of plasticity
Prerequisites
Knowledge of basic terms of theory of elasticity (stress, principal stress, strain, general Hooke's law). Fundamentals of theory of limit states (criteria of plasticity and brittle 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
Active participation in seminars.
High quality elaboration of individual assignments.
Passing the test of basic knowledge.
Aims
Revision of construction of metal materials. Causes of metal material deformation and degradation processes. The theories of plasticity and their formulation in tensor recontouring.
Specification of controlled education, way of implementation and compensation for absences
Attendance at practical training is obligatory. An apologized absence can be compensed by individual projects controlled by the tutor.
