Module Description: The aim of this module is to provide students with an in-depth knowledge of the design process and design evolution of components as well as failure criteria and stress / strain analysis for agricultural components and machinery.
 
Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Describe the stress at a point within a material / component, predicting the behaviour and/or failure of the material / component when subjected to loads with particular emphasis on agricultural applications.
LO2 Apply models of stress / strain to representative agricultural systems in order to determine relationships between loads and the corresponding deflection.
LO3 Develop finite element models of simple agricultural structures to solve for load, deflection and stress.
LO4 Develop mesh generation strategies for two and three-dimensional geometrical arrangements using industry standard software.
LO5 Application of F.E.A. to typical agricultural engineering design problems.
LO6 Quantify, by calculation and experimental measurement, the characteristic response of an agricultural system.
