Failure Reliability and Durability of Polymers

Polymer materials are viscoelastic in nature and their properties are highly dependent on time, temperature and stress. As a simple illustration, the long term fatigue strength of polycarbonate is only 14% of the short term tensile strength quoted on manufacturers’ data sheets. The significance of this is often overlooked at the design stage.

This three day course, deliverered in partnership with MIRCE has been designed for practicing engineers, analysts and managers. It will provide a general understanding of polymers as physical materials, their properties and failure mechanisms, reliability analysis method and methods that should be used in design and production processes to assure desirable durability characteristics.

Course fees - £950.00 + VAT (tuition, course material, lunches and light refreshments).

Course dates - 17^th– 18^th April 2012, 10^th– 12^th July 2012 and 16^th - 18^th October 2012

Venue: Woodbury Park Hotel, Golf and Country Club – (approximately eight miles from Exeter)

Objectives

By the end of this course you will be able to:

Understand what polymers are and what defines the major polymer groups (thermosets, elastomers, thermoplastic elastomers, amorphous thermoplastic and semi-crystalline thermoplastics).

Define and analyse system requirements and determine reliability and durability critical parameters

Understand the short term properties of polymers (stiffness, toughness, strength, HDT) and the effects of time and temperature on performance.

Understand polymer material selection, moulding and design features essential to ensuring the long term durability of engineering components

Perform Reliability Analysis of failure data

Make predictions regarding the future durability characteristics of a given polymer structure
