10 deg Off-Axis Tensile Testing of Carbon Fiber Reinforced Polymers Using Digital Image Correlation

December 5, 2019

Author(s)

Matthias J. Merzkirch, Timothy J. Foecke

The current work describes the use of DIC for full-field strain and deformation response while performing 10° off-axis tensile tests on rigidly clamped unidirectionally carbon fiber reinforced (CFRP-UD) coupon specimens with a nominal reinforcing fraction

Investigation of the Interlaminar Shear Properties of Fiber Reinforced Polymers via Flexural Testing using Digital Image Correlation

December 2, 2019

Author(s)

Matthias J. Merzkirch, Timothy J. Foecke

Determination of the interlaminar properties of laminate composites to date have included a few direct measurement techniques: the standardized short beam test via three-point flexural testing and the double beam shear test via five-point flexural testing

In-Plane Shear Response of GFRP Laminates by +- 45deg and 10deg Off-axis Tensile Testing using Digital Image Correlation

September 23, 2019

Author(s)

Matthias J. Merzkirch, Qi An, Aaron M. Forster

For the determination of the shear strength, strain and modulus of reinforced composites, nearly a dozen measurement techniques exist, several of which are supported by ASTM or ISO standards. One reason for so many options is the difficulty in obtaining a

Characterizing Fiber Reinforced Polymer Composites Shear Behavior with Digital Image Correlation

September 24, 2018

Author(s)

Qi An, Matthias J. Merzkirch, Aaron M. Forster

The interlaminar and intralaminar shear properties, such as modulus and strength, are important for the design of fiber reinforced polymer (FRP) composite materials. Short beam strength is often used as a screening tool for interlaminar strength, but the V

Measurements of Mode I Interlaminar Properties of Carbon Fiber Reinforced Polymers using Digital Image Correlation

July 3, 2017

Author(s)

Matthias J. Merzkirch, Louise A. Ahure Powell, Timothy J. Foecke

Numerical models based on cohesive zones are usually used to model and simulate the mechanical behavior of laminated carbon fiber reinforced polymers (CFRP) in automotive and aerospace applications. The codes of these models require different interlaminar

High Strain Rate Mechanical Characterization of Carbon Fiber Reinforced Polymer Composites using Digital Image Correlations

March 28, 2017

Author(s)

Louise A. Ahure Powell, William E. Luecke, Matthias J. Merzkirch, Timothy J. Foecke, Katherine Avery

The introduction of carbon fiber reinforced polymer (CFRP) composites to structural components in lightweight automotive structures necessitates an assessment to evaluate that their crashworthiness dynamic response provides similar or higher levels of
