Delamination Effect on the Buckling Behaviour of Carbon–Epoxy Composite Typical Aeronautical Panels
Applied Sciences, 2023 The instability of structures due to compression is one of the most critical issues related to aircraft components. Especially in composite materials, which have poor out-of-plane mechanical properties, the buckling load must be assessed to ensure that ...

Impact-induced bonding process of copper at low velocity and room temperature
Materials & Design, 2023 The impact-induced bonding can be foundation of fast solid-state additive manufacturing. The mechanisms behind impact-induced bonding have not been widely acknowledged due to complexity caused by too transient process and extreme loading conditions.

Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]
, 2013 This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

Low velocity impact response and post impact compression behavior of BMI matrix composites
Cailiao gongcheng, 2022 A novel kind of lattice-distributed ESTM-fabrics was developed by using polyethersulfone(PES) and U3160.The loading amounts of PES on ESTM-fabrics are 15 g/cm2(ES-15), 25 g/cm2(ES-25), 35 g/cm2(ES-35), respectively.

Low velocity impact analysis with nastran [PDF]
Computers & Structures, 1991 A nonlinear elastic force-displacement relationship is used to calculate the transient impact force and local deformation at the point of contact between impactor and target. The nonlinear analysis and transfer function capabilities of NASTRAN are used to define a finite element model that behaves globally linearly elastic, and locally nonlinear ...

Low-velocity impact of pressurised pipelines
International Journal of Impact Engineering, 2010 Experimental tests are reported on steel pipelines which have been struck by a relatively large rigid wedge-shaped mass travelling up to 10.4m/s. A pipeline is supported across a span, is fully clamped at both ends and is struck at the mid-span and at the one quarter span positions. Most of the pipelines are pressurised with a nitrogen gas. The initial
