Dear Ahmad Zafari,

Thanks for your answer. We produce the Ti samples in hot press which uses 10 mm radius and 5 mm thickness graphite mold. Because of inadequate dimensions of the sample we prefer to make bending test. We observed good bending result but also we need to observe the E modulus, because it is very important for biomedical applications.

Dear Erdinç,

Although most people measure the elastic modulus from tensile or compression tests, as Ahmad Zafari commented, the most recommended experimental method for measuring the elastic modulus (Young Modulus E) is in fact in flexion or bending. However the method is not static, but dynamic, through the resonance frequency of a small plate estimulated to vibrate in flexion. The equations for this kind of measurements can be found in many textbooks. I give you a reference: M. F. Ashby & D.R.H. Jones, Engineering Materials Vol. 1, Pergamon Press, Oxford, (1980), ISBN 0-08-026138-8. There has been many editions of this clasic textbook. In the first edition, the method is described in pages 30 and 31.

There are some companies that furniss simple equipment for this kind of measurements, which could be very well adapted to the size of your samples, and for room temperature measurements they are not expensive. Please let me know if you would like more information about. I give you one website that comercialize this kind of equipment: http://www.imce.eu/
