| Abstract: | The tensile specimen shapes are roughly induced to columnar and laminar structures by contrasting and describing the shapes of the different material tensile test specimens.The suitability of the two kinds of structural shapes in the different material tests is analyzed.Several means and methods for evaluating the suitability of tensile test specimen structures in the current material fields are summarized.And the importance of the tensile property testing in the material science research is discussed. |
