This document introduces the influence of the s-s diagram on the pass/fail judgment of KIc. In ASTM D5045, it begins with a "preface" stating that the provisional fracture toughness value KQ can be regarded as KIc, and provides detailed descriptions of "the characteristics of the resin's s-s diagram" and "how to determine the provisional fracture toughness value KQ." Additionally, "references" are also provided, so please take a moment to read through them. 【Contents (partial)】 ■ Preface ■ Characteristics of the resin's s-s diagram ■ How to determine the provisional fracture toughness value KQ ■ Numerical analysis regarding KQ,pl ■ The influence of E/σ0.2 and n on the nonlinear behavior of the load-opening displacement diagram *For more details, please refer to the PDF document or feel free to contact us.

This document introduces the organization and discussion of the factors influencing the KIc of resins. It provides a detailed explanation of "factors affecting KQ (KIc)" and "the characteristics of the s-s curve of resins and their impact on KQ." In the "Conclusion," it is stated that the size of the plastic zone formed near the crack tip is sufficiently small compared to the size of the test specimen, and additional "References" are also included. We encourage you to read it. 【Contents】 ■ Preface ■ Published literature on the KIc testing of resins ■ Factors affecting KQ (KIc) ■ Characteristics of the s-s curve of resins and their impact on KQ ■ Conclusion ■ References *For more details, please refer to the PDF document or feel free to contact us.

This document introduces a comparison between the KIc tests for resins according to ASTM D5045 and the KIc tests for metallic materials according to ASTM E399. It provides an overview of the testing method of ASTM D5045 in contrast to ASTM E399, including a "preface" that explains the use of standard test specimens such as Compact Tension (CT) specimens and three-point bending (SENB) specimens, which are permitted in both ASTM D5045 and ASTM E399. This book is designed to be a useful reference during the consideration of implementation, so please take a moment to read it. 【Contents】 ■ Preface ■ Fracture Toughness Test Specimens ■ Testing ■ Conclusion ■ References *For more details, please refer to the PDF document or feel free to contact us.

"Material Property Evaluation" is a materials testing process that assesses the characteristics (material properties) of materials. Measurements can be taken from sample polishing and corrosion, collection of metallographic data (macro and micro) using optical microscopy, measurement of "hardness," one of the mechanical properties of metallic materials, using a hardness tester, and it is also possible to compare material properties through heat treatment using an electric furnace. 【Measurement Methods】 ■ Measurements through sample polishing, etching, and corrosion ■ Measurements using a hardness tester ■ Comparison of material properties through heat treatment using an electric furnace *For more details, please refer to the PDF document or feel free to contact us.

"Fatigue testing" is a material test that evaluates the durability of materials by applying various loads to the test specimen. It is said that most causes of failure accidents are due to fatigue failure, and with the increase in structures over 50 years old in recent years, the importance of fatigue testing is growing. At Shimizu Tech, we respond to the need for rapid test results with our well-equipped facilities and highly reliable technology. [Test Methods] ■ Room Temperature Fatigue Test ■ High-Temperature Fatigue Test / Thermal Fatigue Test ■ Bending and Torsion Fatigue Test ■ Rotating Bending Fatigue Test *For more details, please refer to the PDF materials or feel free to contact us.

The "Tensile and Compression Test" is a material test that evaluates "strength" within the information of "mechanical properties" for metal products and components. Materials have different properties depending on their types. It measures how much durability they have against external forces and environments such as tension, compression, and shear. The data obtained from the measurements is referred to as "mechanical properties" and serves as an important indicator for evaluating the processing methods of materials and the durability of processed products. [Test Methods] ■ Room Temperature Test ■ High-Temperature Test ■ Compression-Torsion Test *For more details, please refer to the PDF materials or feel free to contact us.

• Contract Inspection

Our company has been engaged in the research and development of metal materials for over 60 years. Craftsmen in each section are well-versed in the important processing points assigned to each test specimen, and by using suitable processing methods to obtain accurate test results, we produce highly reliable test specimens that cannot be compared solely by appearance. 【Lineup】 ■ Test specimens ■ Low-stress test specimen processing ■ Jig design *For more details, please feel free to contact us.
