Dynamic fracture mechanics

Submitted by Cai Shengqiang on

Dynamic fracture mechanics is written by a very well known professro-L B Freund. Honestly, I have only read a small part of the book. However, I recommend this book because after reading this book, you can learn many things which haven't be touched in the class, as stated by Zhigang in the beginning of the class.

Hi......

       I have a accelaration vs time data for an earthquake. But I need velocity vs time data for an earthquake for dynamic analysis of a structure with this earthquake as input. The intrgration of accelaration is velocity. How I can integrate this numerical data? I have an idean about Newmarks beta method but how to use it? I have no idea. Is there any further simple method to do this? Is there any reference book or journal or link available for this?

Thanks in advance......
