Impact Strength in Dinamic Bending as a Function of the Strength in Static Bending of Wood

open access: yesInternational Journal of Materials Engineering, 2018
Wood is a natural, renewable and abundant material in Brazilian territory. But its use in civil construction is still commonplace. When compared to materials such as steel and concrete, it has many advantages, such as its resistance to density ratio. Where it is possible to observe a high resistance, equivalent to concrete of high performance with a ...

Residual Bending Strengths of CFRP Laminates after Impact

open access: yesJSME international journal. Ser. A, Mechanics and material engineering, 1995
In this paper, static and fatigue residual bending strengths of carbon fibre reinforced plastic (CFRP) laminates having impact damage are evaluated with four- and three-point bending tests. A steel ball was launched from an air gun and impacted upon CFRP laminates to generate impact damage.
