The Theory & Practice of Developing Rubber Products with Good Fatigue Life

pic 2Star Hydraulics, Tewkesbury, 6 October 2016

The aim of the course is to give those who design, make and use rubber products an understanding of underlying principles about the ways the materials deform and factors that affect fatigue life. The course will explain the structure of rubbers and how the different parts of the mixture can affect the fatigue life.
The effect of different types of loading such as the effect of minimum strain and the differences between uniaxial and biaxial loading will be discussed for different types of rubbers.

Fatigue of rubbers is complex but the course provides a foundation of knowledge so that improvements in fatigue life can be planned and executed. The course provides the basis of knowledge needed for further courses that will cover some specific aspects of fatigue in more detail.

The course will be led By Dave Boast FIMechE of DB Engineering. Dave has over 35 years of experience of a wide range of elastomer products in many industries in demanding applications. He has organised many events for the Rubber in Engineering Committee of the Institute of Materials to promote the understanding and science of rubber manufacturing and products
