  2. Calculation of glass properties - Wikipedia

    en.wikipedia.org/wiki/Calculation_of_glass...

    The calculation of glass properties allows "fine-tuning" of desired material characteristics, e.g., the refractive index. [1]The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save ...

  3. Hollow structural section - Wikipedia

    en.wikipedia.org/wiki/Hollow_structural_section

    In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than ...

    Generally, the Lankford value of cold rolled steel sheet acting for deep-drawability shows heavy orientation, and such deep-drawability is characterized by .However, in the actual press-working, the deep-drawability of steel sheets cannot be determined only by the value of and the measure of planar anisotropy, is more appropriate.

  5. Specific modulus - Wikipedia

    en.wikipedia.org/wiki/Specific_modulus

    It is also known as the stiffness to weight ratio or specific stiffness. High specific modulus materials find wide application in aerospace applications where minimum structural weight is required. The dimensional analysis yields units of distance squared per time squared.

  6. Shading coefficient - Wikipedia

    en.wikipedia.org/wiki/Shading_coefficient

    The shading coefficient depends on the color of glass and degree of reflectivity. It also depends on the type of reflective metal oxides for the case of reflective glass. Sputter-coated reflective and/or sputter-coated low-emissivity glasses tend to have lower SC compared to the same pyrolitically-coated reflective and/or low-emissivity glass.

    President Joe Biden is commuting the sentences of nearly 1,500 people and pardoning 39 others in "the largest single-day act of clemency in modern history," the White House announced Thursday ...

  8. Tube drawing - Wikipedia

    en.wikipedia.org/wiki/Tube_drawing

    Tube sinking, also known as free tube drawing, reduces the diameter of the tube without a mandrel inside the tube. The inner diameter is determined by the inner and outer diameter of the stock tube, the outer diameter of the final product, the length of the die landing, the amount of back tension, and the friction between the tube and the die.
