    replacing bone and mimicking their structure for, various applications. When looking at biological materials, to determine their effectiveness as a scaffold or sufficient structure for various other uses, often they are tested for their resistance to fracture. This is referred to as fracture propagation. Bamboo Bamboo is well known for its sufficient mechanical properties, and great flexibility. It also has great fracture toughness. Bamboo is considered to be a bio composite, meaning it encompasses multiple biological features and traits. It has a honeycomb structure of fibers, along with the cellular configuration of a parenchyma ground. Within the bamboo culm, there are hollow vessels that help pass nutrients throughout the plant.

  • Lab Analysis Of The 4PB Experiments

    ERRs Gc (i.e. interfacial fracture toughness) of the interface between Cu leadframe and EMC. They were determined by the FEM simulations using the three mentioned methods: VCCT, VCE and J-integral. The verification of simulations was performed using an analytical solution (eq. (6)). Based on the critical ERRs obtained from different specimens tested at different temperatures, the temperature dependence of the interfacial fracture toughness was investigated. The upper EMC layer of the sample was…

  • Multi Stage Fracturing Research Paper

    Multi-stage fracturing is an advanced drilling technology that enhances the production capabilities through maximizing the contact area of unconventional wells with the reservoir production zones. During the fracturing process, a special fluid (primarily a mixture of sand and water) is blown out at a high pressure into the shale rock formation creating channels through which hydrocarbons can easily migrate to the well. Multi-stage fracturing is a combination of fracturing and plugging processes.…
