- The objectives of this thesis is to predict the mechanical behavior of bulk clad metal welded by explosion. The clad is composed of corrosion resistant alloy coating and stainless steel 316 affiliation.
Commonly bulk clad material is used as a structural material experiencing warm temperature. It is important for clad combined more than two different thermal expansion coefficients to be measured separately in location when thermal analysis evaluation is implemented. However this locally separated specimen should be confirmed whether it represents the whole clad material behavior properly. To measure the whole mechanical behavior of bulk clad material, unusual specimen shape was designed. This thesis attempts to predict the whole mechanical behavior from divided partial properties.
Consequently, individual properties can predict the whole mechanical behavior not only short deformation range but also large deformation range at room temperature and warm temperature very well.
