The material properties of polymers like plastics and elastomers can be affected by their environments and weaken over time. These changes can lead to premature product failure. It is, therefore, important to perform material characterization and age testing prior to making a new product. EWI Senior Technology Leader Jeff Ellis has written Predicting Polymer Service...

By James Cruz, EWI An example of a PVC-aluminum laser weld. Just try to break this! My first job out of college at Honda of America Manufacturing was a dream come true—the chance to play with robots and build cars! They handed me several crisp, white uniforms on day 1. Within that first week on the production...

The H-coupon test, developed a few years ago to evaluate cracking behavior in spot-welded advanced high-strength steels (AHSS), has recently been applied to galvanized third generation AHSS. Two types of cracking have been observed in the tests of these steel grades – interfacial and zinc liquid metal embrittlement (LME). This research is discussed in Application...
