Destructive testing

             The main purpose of destructive testing is to obtain a complex  mechanical properties characterising the quality of materials by destructing of samples produced of the materials used.
            The testing is performed under strict conditions, using special laboratory equipment and precise dimensions of the test peaces. The destructive testing can verify the guaranteed mechanical properties of the material.

tensile test The tensile test is based on applying tensile force to the tested samples until the material is destroyed. This is done to determine one or more mechanical properties (strength and plastic characteristics).
 
     
Yield stress Yield stress is determined depending on the type of diagram obtained. Higher yield stress (ReH) and lower yield stress (ReL) are determined for test pieces that produce a diagram with a “yield stage”. For test pieces producing a diagram without a “yield stage”, offset yield stress (Re) is determined.  
     
Tensile testing Tensile testing allows the ultimate elongation at rupture A (percentage permanent elongation) and shrinkage in area at rupture Z (maximum percentage reduction in cross-sectional area) to be determined  
 
Bend test
 
Bend test consists of submitting a test piece to a load provoking bending. The bending continues until a specified angle of bend is obtained or the piece is destroyed or cracking appears.  
     
Charpy The Charpy impact test consists of breaking a test piece notched in the middle and supported at both ends using a single blow from a swinging pendulum. The energy absorbed is determined in joules. This absorbed energy is a measure of the impact strength of the material.  
     
Macro and Microstructures The method consists of visualization and evaluate Macro and Microstructures of metals.
These methods allow determination of, qualitative and quantitative analyses, micro defects and others.
