Application of EDM hole-drilling method to the measurement of residual stress in tool and carbon steels
Article Abstract:
The study adopts the application of the electrodischarge machining (EDM) hole-drilling method to the measurement of residual stress in AISI D2 old work tool steel, AISI HI3 hot work tool steel, and AISI 1045 medium carbon steel. The experimental results reveal that combination of the hole-drilling strain-gage method with an EDM drilling process provides the effective means of determining the residual stress in materials with high hardness and good wear resistance.

Stress relaxation behavior at high-tension bolted connections of stainless-steel plates
Article Abstract:
The measurements of creep strain and residual stress in the bolt are made to clarify the influence of creep deformation of stainless-steel plates on the stress relaxation at high-tension bolted connections. The experimental results would be compared with numerical ones produced by finite element method (FEM) using the creep equations derived from the constant load creep experiments.

Experiments and numerical simulations on thin metallic plates subjected to an explosion
Article Abstract:
The mechanical response of the metallic plates and simple geometrical structure to evolve in high strain rate dynamic methods are used for analytical and numerical studies. Three different constitutive laws are discussed and the identification of constitutive parameters is made using unidirectional tests on the studied material.
