摘      要：This paper reports an experimental study of the mechanical response to tensile and compressive force of large scale steel to composite joints adhesively bonded with a thin layer of vinylester *** one specimen,the length of the reinforcing fibres in contact with the steel substrate has been reduced by saw cutting at both ends of the *** damaged specimen and four intact specimens were subjected to quasi-static tensile testing;six specimens were used for compression *** strain distribution at the composite surface and at the steel to hardwood connection of the specimen was monitored by digital image correlation(DIC).DIC allowed identifying the onset of damage in the tensile tested joints near the interface of the composite layer and the steel-hardwood *** tensile and compression tested specimens failed due to significant peel strain concentration at the composite near the connection of steel and *** average strength of a specimen tested in compression was about 66%higher than the average strength of a specimen tested in *** strain concentration zone in the damaged specimen was away from the introduced saw *** a result the damaged and intact tensile specimens showed the same failure strength and *** specimens failed by adhesive failure between the composite-hardwood interface.
