It depends on the ceramic. Most ceramics have fracture toughness between 0.7 AND 1 MPa - m^1/2. Some are lower, and some higher, up to 5 MPa-m^1/2
jagged, torn, imperfect
ceramic is made of pure heat over 100c and bits of gravel and stone its ,made in a large stone oven called kiln. cement is mostly made of a mixture of elements that are found in natural materials.
Yes, there is a difference between HCR (High Carbon Steel) and HCRM (High Carbon-High Chromium Steel). HCR typically contains a higher percentage of carbon, making it harder and more wear-resistant, while HCRM includes chromium, which enhances corrosion resistance and improves toughness. This makes HCRM suitable for applications requiring both hardness and resistance to oxidation. Overall, the addition of chromium in HCRM tailored its properties for specific industrial uses.
Hitachi Blue Steel, also known as Aogami, is a high-quality tool steel produced by Hitachi Metals. It is renowned for its exceptional hardness, edge retention, and ease of sharpening, making it a preferred choice for high-performance kitchen knives and other cutting tools. The steel is typically alloyed with high carbon content and small amounts of chromium and tungsten, which enhance its durability and resistance to wear. Two primary variants, Aogami #1 and Aogami #2, offer different balances of hardness and toughness for various applications.
ER 90SB2 is a type of welding filler metal used primarily for joining high-strength steels. The designation "ER" indicates that it is an electrode rod suitable for use in gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). The "90" signifies its strength level, while "SB2" indicates specific chemical compositions and mechanical properties tailored for applications requiring high toughness and strength. This filler is commonly used in industries such as construction, manufacturing, and automotive, where strong and durable welds are essential.

The fracture toughness, or the property that describes the ability of a material containing a crack to resist fracture, of mild steel is around 50 K (where 'K' is the stress intensity factor).
By learning and listening in class instead of pissing about?
It shows the fracture toughness of materials. higher the brittleness lower the fracture toughness and also lower will be the impact value and vice verse.
Impact test gives toughness value which is energy absorbed by material per unit volume.. From test like charpy test value of energy absorbed by the specimen can be calculated directly by getting the height of pendulum after impact.... whereas fracture toughness is totally different subject which comes into picture after formation of crack in the material. Methods of calculation of fracture toughness depends upon the type of material (brittle or ductile). Resistance curve is used to find the fracture toughness.

It is the English units for Fracture Toughness (K1c) of a specific material.
