In this chapter are discussed aspects related to the damage evolution in wood and in plywood with acoustic emission technique and with digital imaging technique. Digital imaging creates a digital representation of the visual characteristics of a specimen under mechanical test. The techniques of digital imaging and of finite element analysis can be used for locate and images of tip crack propagation.

摘要

In this chapter are discussed aspects related to the damage evolution in wood and in plywood with acoustic emission technique and with digital imaging technique. Digital imaging creates a digital representation of the visual characteristics of a specimen under mechanical test. The techniques of digital imaging and of finite element analysis can be used for locate and images of tip crack propagation.
