Damage accumulation of bovine bone under chaotic and variable amplitude loading.
… The Moon's Beam experimental set-up was used to test chaotic loading conditions. The variable amplitude set-up was utilized to test variable amplitude loading conditions. Lastly, a four-point bend test was used to determine the baseline properties of the bone tissue. Scanning electron microscopy …

Characterization and requirements for Cu-Cu bonds for three-dimensional integrated circuits
… quality under a range of loading conditions. The four-point bend test was used to quantify Cu-Cu bond toughness, Gc, under mixed-mode loading and to develop an optimized process flow that enabled the creation of high- toughness bonds (> 5 J/m2) at a bonding temperature of 300 oC. Mixed-mode …

On the oxidation of high-temperature alloys, and its role in failure of thermal barrier coatings
… at which crack initiation occurs in a notched four-point bend test experimentally studied in the literature, as well as the overall qualitative load-displacement behavior in this test.

Characterization of bonded copper interconnects for three-dimensional integrated circuits
… during processing and also during service. A four-point bend test technique has been used to evaluate the strength of Cu-Cu bonds. Test structures were fabricated by bonding wafers containing copper lines (with Ta barrier) that were patterned on silicon dioxide. Tests on the …

Supersonic Laser Deposition and LaserForge: Process Mechanism Coating Characteristics
… scanning electron microscope. A tensile pull off test was used to measure the coating adhesion, and a four-point bend test with acoustic emission was used to monitor the failure of the coating. Plastic failure of the coating was identified, and a test limited adhesion strength in excess of 70 MPa …

Dynamic delamination of patterned thin films
… of the thin film/substrate interface. The testing method involves using a laser-induced acoustic stress wave to load the film/substrate fracture plane in tension at very high strain rate (~10^7/s) leading to the inertia-driven interface delamination. A weak adhesive layer is selectively …

Mechanical characterisation of float and laminated glass
… strength of FG and LG when subjected to the four-point bend test (FPBT) and the ring-on-ring (ROR) test. This will aid in developing guidelines that account for size effects in structural design, ensuring safer and more reliable use of glass materials in engineering and architectural …
